[Solved] Pipewire cuts out frequently but randomly and needs a restart

For the last several months since installing Arch on my desktop, I have been running into a very frustrating and seemingly-random audio bug with my USB headphones. Most of the time, the audio stack (Pipewire, Wireplumber) works perfectly. However, semi-frequently and seemingly at random (anywhere from once to 4 times per day on average), all sounds stop coming out of the headphones entirely.

A workaround that almost always fixes the issue is to restart either Pipewire or Wireplumber with systemctl. However, whenever I do that, I have to restart applications to get their sound to continue working, and it frequently breaks again immediately as soon as I restart.

I've been hitting my head on this for a while now, so here are all of the findings I have so far. Nothing has ever fixed the issue beyond "it stopped happening for a few days and then started again".

Circumstances of the issue:

  • It only happens on my Arch installation. I used the dongle on Windows on the same PC with no such problem for a few years before switching to Arch.

  • I also have a laptop that runs roughly the same Arch stack (packages, configs, etc.). I use the same dongle on that laptop and have never run into any issues like this. (So this isn't purely a hardware issue)

  • Sound only cuts out on this specific sound device. When it happens, I can still make volume level feedback sounds play on all other devices through KDE's volume mixer.

  • Applications "know" that the sound is not working. For example, YouTube videos stop playing and start an endless buffering animation, and the KDE volume mixer does not give any visual indicator of sound levels playing on the device like it normally does.

  • I have loosely associated the incidence of the issue with a new application starting or stopping sound playback. For example, the sound stops working more frequently than random chance when changing songs (playing in Firefox) or launching a new program that uses audio. This is not 100% though, because on many occasions, I will be doing nothing on the PC other than listening to something or speaking on a Discord call when it cuts out suddenly.

  • When the issue happens, it tends to happen many more times in succession. For example, if the sound cuts out in the middle of a Discord call, and I go through the process of restarting Pipewire and Discord, re-joining the call will immediately cause sound to cut out again (even if I verified with the audio mixer feedback that it was working right before re-joining the call). This cycle might happen anywhere between one and ten times in a row (not an exaggeration). Rebooting does not break the cycle.

Some things I've tried, but still eventually run into the issue in every one of these setups:

  • Plugging the dongle into other USB ports on the back of the PC, front of the PC, USB 3.0 ports, 3.2 ports, 2.0 ports...

  • Updating to the latest BIOS version

  • Installing wireplumber-git and pipewire-git

  • Switching to pipewire-media-session (removing wireplumber)

  • Switching to the Zen kernel

  • Applying various Wireplumber configuration changes at `/etc/wireplumber/main.lua.d/50-alsa-config.lua`, including:

    • api.alsa.period-size

    • api.alsa.headroom

    • session.suspend-timeout-seconds (I set to 0 to disable suspend)

  • Adding amd_iommu=off as a kernel parameter per this suggestion

The only things left I can think to do are do a fresh Arch install, or get a new headset.

Environment Details:
Audio-related packages as of today:

$ pacman -Q | grep -e pipe -e jack -e pulse -e wire -e alsa  
alsa-card-profiles 1:1.0.1-2  
alsa-lib 1.2.10-2  
alsa-plugins 1:1.2.7.1-2  
alsa-topology-conf 1.2.5.1-3  
alsa-ucm-conf 1.2.10-2  
alsa-utils 1.2.10-1  
kpipewire 5.27.10-1  
lib32-alsa-lib 1.2.10-2  
lib32-alsa-plugins 1.2.7.1-2  
lib32-libpulse 17.0-1  
libpipeline 1.5.7-1  
libpipewire 1:1.0.1-2  
libpulse 17.0-3  
libwireplumber 0.4.17-1  
pipewire 1:1.0.1-2  
pipewire-alsa 1:1.0.1-2  
pipewire-audio 1:1.0.1-2  
pipewire-jack 1:1.0.1-2  
pipewire-pulse 1:1.0.1-2  
pulseaudio-qt 1.4.0-1  
wireplumber 0.4.17-1  
wireshark-cli 4.2.2-1  
wireshark-qt 4.2.2-1

Non-audio-related packages:

linux 6.7.1.arch1-1      (tried with both kernels)
linux-zen 6.7.1.zen1-1

plasma-desktop 5.27.10-1  (running in Wayland)
xorg-xwayland 23.2.4-1  
xwaylandvideobridge 0.4.0-1

  • Motherboard is a MSI MAG B550 Tomahawk

  • CPU is a Ryzen 9 5900X

  • The USB headset is connected through a Creative BT-W2 dongle. This is a Bluetooth dongle, but it does not expose itself to the host's Bluetooth stack at all - Linux only sees a USB sound device.

refind kernel parameters: 

"root=UUID=(REDACTED) rw rootflags=subvol=@ initrd=@\boot\amd-ucode.img initrd=@\boot\initramfs-%v.img resume=UUID=(REDACTED)"

Finally, here are a few command outputs:

  • lsusb on the headset device

  • systemctl outputs on one instance of it happening

    • Notable errors:

      pipewire[1272]: mod.client-node: 0x5790e6295860: unknown peer 0x5790e6a03f70 fd:112
pipewire-pulse[1401]: mod.protocol-pulse: client 0x5f44100d7b60 [Plasma PA]: ERROR command:-1 (invalid) tag:815 error:25 (Input/output error)

  • Other errors I've picked out of journals on various occurrences of the issue, which line up with when the sound cut out:

    pipewire[17552]: mod.client-node: 0x61016b92f890: unknown peer 0x61016b534f30 fd:106
    pipewire[6538]: spa.alsa: front:2p: (125 suppressed) snd_pcm_avail after recover: Broken pipe

Thank you sincerely to anyone who has read through all of this. I would thoroughly appreciate any further tips for where I might look to help determine what exactly is happening or how to prevent it happening.

Re: [Solved] Pipewire cuts out frequently but randomly and needs a restart

Since everything works on your laptop, I'd try copying your wireplumber config from there to your desktop.
Also, I'd look into Linux kernel's USB autosuspend. USB Power Saving.
I'm not an expert, though, and those are just wild guesses.

My laptop has no Wireplumber config in either /etc/wireplumber or ~/.config/wireplumber. I deleted the configs on my desktop and will update if I run into it again.

It looks like power saving is already disabled by default on this device, I don't have any udev rules that are setting it.

$ cat /sys/bus/usb/devices/usb1/1-3/idProduct          
3125   (this matches the output of lsusb I linked above)
$ cat /sys/bus/usb/devices/usb1/1-3/idVendor 
041e   (this matches the output of lsusb I linked above)
$ cat /sys/bus/usb/devices/usb1/1-3/power/control 
on

I appreciate the pointers!

Re: [Solved] Pipewire cuts out frequently but randomly and needs a restart

Unfortunately, even with no added Pipewire or Wireplumber config in /etc or ~/.config, I still hit the issue.

Re: [Solved] Pipewire cuts out frequently but randomly and needs a restart

Is this actually a problem with pipewire or with the kernel driver. When this happens post 

sudo fuser -v /dev/snd/*
aplay -lL
lsusb -t
sudo journalctl -b

FWIW usb based audio devices are also quite prone and react allergic to insufficient power on the USB bus. If this is plugged into some hub or similar try to plug it somewhere different (looking at the lsusb -t, it should best be alone on a USB 2+ capable hub)

FWIW2 lol,creative I'd not put it past them if they have some stupid firmware logic that suspends/breaks the device if it wasn't receiving audio for a while. Or does this actually actively happen while sound should be playing?

I'll try these next time it happens!

I will give it a try on other ports again, but I did run into it at least once on several different ports on both the motherboard and case. Standard setup is that it's the only thing plugged into any of the case ports.

It does happen suddenly every once in a while while sound is actively playing and not changing at all. However, it is definitely more common to see when sounds start or stop.

I tried again in various different ports, no change. This output is with it in a motherboard 3.2 port.

One interesting note the most recent time it happened is that as soon as I quit Discord, the sound came back and I heard the queued feedback sounds from the KDE volume mixer. So these sounds are getting queued somewhere, but blocked from making it to the output and "released" when Discord is closed. Maybe Discord is the problem?

Always.

Re: [Solved] Pipewire cuts out frequently but randomly and needs a restart

Unfortunately, I still did hit the issue without Discord, but it seemed much less frequent. Probably because Discord likes to open and close audio devices frequently.

I bought a $13 TP-Link Bluetooth dongle from Amazon and have been using it instead of continuing to try to debug. I haven't hit the issue at all in the last few days of using it. (I originally used the Creative one since it supported aptX Low Latency, but Linux's Bluetooth stack gives the same codec option with this adapter and identical quality, so I'm not really missing anything with the new dongle.) Sorry for anyone else who hits a similar issue reading this in the future, but I don't think I'm going to try to debug this any further. Clearly something about the Creative adapter acting as a plain USB sound device didn't play well with Linux.

Re: [Solved] Pipewire cuts out frequently but randomly and needs a restart

In my case, the external 5-volt DAC power supply was causing the sound to be muted. Works perfectly from USB smile

Re: [Solved] Pipewire cuts out frequently but randomly and needs a restart

Creative in general is very whacky on linux most of the time I'm afraid, unless you opt for older/professional studio cards. Had a built in creative sound card that never really worked on my previous mainboard that I replaced with a cheap Xonar DGX. So while this isn't really a satisfactory conclusion, chances are this is just Creative being  "creative" (in a bad way roll)

@Archtilla  For the future please don't fullquote posts if it's not strictly necessary.

Re: [Solved] Pipewire cuts out frequently but randomly and needs a restart

@jtprince, I've been running into a similar problem but with a different device -- Jabra 510 speakerphone. I was having a similar thought: "this USB sound device doesn't play well with Linux [anymore]". Problem for me is, I don't experience the issue on a different computer with a newer motherboard/chipset, and the issue only started last year whereas I've had the Jabra for years.

Your troubleshooting skills are admirable -- I've tried many of the same things. After I found your post yesterday, I found another one that finally did the trick for me. I set these 3 lines of pipewire config

        default.clock.quantum     = 2048
        default.clock.min-quantum = 1024
        default.clock.max-quantum = 4096

and the dreaded 

snd_pcm_avail after recover: Broken pipe

finally stops and the Jabra now works great.

I don't know what a quantum is (I'm a pipewire newb) or what this config actually does, but it seems like they are on to something in this thread. https://gitlab.freedesktop.org/pipewire … ssues/1984

Sharing in case you want to give it another try with this config change. I'd certainly be interested to know if it helps.

One month later, and incredibly, I'm pretty sure this fixed it for good! I had to switch back to the Creative dongle and it hasn't cut out a single time since I set these in /etc/pipewire/pipewire.conf. It's either that, or the 0.5 wireplumber update, but I'm definitely leaning towards higher quantum values being the fix. Thank you so much for the tip!

Re: [Solved] Pipewire cuts out frequently but randomly and needs a restart

Thought I'd chime in.  I struggled with this issue forever with my Tascam model 12 mixer USB interface.

Notice this line in pipewire status:

Archttila wrote:

● pipewire.service - PipeWire Multimedia Service
     Loaded: loaded (/usr/lib/systemd/user/pipewire.service; disabled; preset: enabled)

I found enabling the service solved all audio cutoffs for me.

systemctl --user enable pipewire.service
systemctl --user enable pipewire-pulse.service

Seems simple, but it was PITA to figure out.
Not sure why it's not fully enabled by default after installing pipewire.
