[SOLVED]Alsa with external USB sound card and external USB bluetooth

Dear all!

I tried a lot of things to solve my sound problem but without any luck. I have pretty old laptop. but Arch is running well on it. Laptop has no built in bluetooth adapter, and the audio jack outoput is also damaged, so I solved it with external USB soundcard and with USB bluetooth adapter. On USB soundcards jack output there is a headphone connected, and as bluetooth  I would like to use my Samsung Galacy Buds Live. I also want to use alsaequal.
As I mentioned I tried a lot of things, even pipewire, but sound was awful on my both headphones. Previosly I installed bluez, bluelasa (and bluez-alsa-git as well), blueman. Now are installed: bluez-git, bluez-alsa-git, bleuman-git, alsaequal.
Here is my asound.conf file (I don't use .asoundrc):

# Alapértelmezett eszköz az EQ-val
pcm.!default {
    type plug
    slave.pcm "bluetooth_or_usb"
}

ctl.!default {
    type hw
    card 0
}

# ALSA equalizer
pcm.eq {
    type plug
    slave.pcm "plugequal"
}

ctl.eq {
    type equal
}

# Alsaequal beállítás
pcm.plugequal {
    type equal
    slave.pcm "bluetooth_or_usb"
}

# Bluetooth prioritásos váltás
pcm.bluetooth_or_usb {
    type multi
    slaves.a {
        pcm "bluetooth"
        channels 2
    }
    slaves.b {
        pcm "usb_or_speaker"
        channels 2
    }
    bindings.0.slave a
    bindings.0.channel 0
    bindings.1.slave a
    bindings.1.channel 1
}

# USB vagy hangszóró kiválasztása
pcm.usb_or_speaker {
    type plug
    slave.pcm "usb"
}

pcm.usb {
    type hw
    card 0
}

pcm.speaker {
    type hw
    card 1
}

# Bluetooth eszköz
pcm.bluetooth {
    type bluealsa
    device "34:82:C5:AE:6F:2B"
    profile "a2dp"
}

ctl.bluetooth {
    type bluealsa
}

I used ChatGPT for this one (and for some other ones). The result is, if bluetooth is connected the  the sound is awful (before, with some other configuration it was not the problem):

aplay -D bluetooth /usr/share/sounds/alsa/Front_Center.wav
Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
ALSA lib bluealsa-pcm.c:817:(bluealsa_drain) Drain timed out: Possible Bluetooth transport failure

When bluetooth is off, then no sounds on wired headphones or laptop speakers.

Here is my play -l output:

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Device [USB Audio Device], device 0: USB Audio [USB Audio]

And here is my aplay -L output:

    7.1 Surround output to Front, Center, Side, Rear and Woofer speakers

Can anybody help to solve my issue. I really spent a lot of hours during the weekend and last week but cannot solve. So what I would like to be the result is that if my Buds Live is connected then the system use bluetooth, if not then the system to use USB, and if no bluetooth or USB then laptop speaker. I want to use alsaequal, and I don't want to use pipewire. Mostly I will listen music with Google Chrome on Plex or Youtube.

Re: [SOLVED]Alsa with external USB sound card and external USB bluetooth

I strongly suggest you drop all of this, especially if you rely on ChatGPT for config information, and just use pipewire-pulse, pipewire-alsa, wireplumber which will make this correct and trivial and do exactly what you expect. Doing stuff dynamically and reacting to BT headphones appearing or disappearing is nigh impossible with ALSA alone and if so, you need to restart applications before you can switch output devices.

If it doesn't and the issues limit themselves to BT. bluetooth in general is a very flaky protocol, but chances we can properly fix this in pipewire/pulse are much higher than with static ALSA config. Assuming you switched properly, and things are unsatisfactory, post the outputs of 

pactl list cards
pactl list sinks
pactl list sink-inputs

If you absolutely don't want to do this, create two distinct config files one dedicated to BT playback and one dedicated to non-BT and swap them whenever you connect/disconnect the BT headset.

Re: [SOLVED]Alsa with external USB sound card and external USB bluetooth

Okay, I'll try again pipewire to solve this. What I have iisues with this that during the weekend I did not have my usb soundcard so I cannot try with that. I cannot setup a2sp profile to bluetooth (this is why I switched to bluez-git) and the sound was awful both on bluetooth and wired headphone.

Here are the outputs:

$ pactl list sink-inputs

has no output


I also will need some kind of graphic equaliser, tried easyeffect but got no good result with presets I found on github

Re: [SOLVED]Alsa with external USB sound card and external USB bluetooth

With pipewire now I have sound on my headphone connected  to usb soundcard (just eq is necessary, is the jamesdsp good?) but no sound on bluetooth device, even it is connected the sound is through wired headphone

Re: [SOLVED]Alsa with external USB sound card and external USB bluetooth

As for switching where something plays back to, I suggest you install pavucontrol or so which gives you a gui where you can freely move around what plays where. (and pactl list sink-inputs will give you output if you actively play something somewhere)

Your main problem is that the Galaxy Buds appear to not advertise an a2dp profile (which leaves you with mono which is simply going to sound like shit), which could be a bug from them, a bug in your own BT dongle, something in the kernel or something in pipewire or something in bluez... you see BT is anything but trivial.

General problems in the last three would make much bigger waves here. so limits us to looking at your system.

Are the galaxy buds connected to anything else, e.g. your phone at the same time? Can you disable BT there and properly reconnect/re-pair the headphones to the Arch host to ensure there's no interference there? Did you use the same buds with the same BT dongle on another system e.g. a dual booted Windows or so? All of these are things that can leave the HW in undefined states and should be avoided if possible.

sudo journalctl -b | grep -iE 'bluez|btusb|Bluetooth'
sudo journalctl -b -u bluetooth
journalctl -b --user-unit pipewire --user-unit wireplumber
lsusb -t

As for EQ, yes I've heard good things about jamesdsp, personally I have only experience with easyeffects which is also quite good.

Re: [SOLVED]Alsa with external USB sound card and external USB bluetooth

Bluettoth earplugs are paired with my phone and with my TV but not connected at the same time while it connected to laptop and Arch. Also BT dongle is used only with this laptop, no other usage.

Here are the outputs:

Re: [SOLVED]Alsa with external USB sound card and external USB bluetooth

Try getting the conflicting daemons out of the way, make sure bluez-alsa is  not interfering.

Re: [SOLVED]Alsa with external USB sound card and external USB bluetooth

Can you please help me how to do that? Can I find some wiki pages about this?
Should I change bluez.lua to new format? Now it is looks like:

bluez_monitor = {
    properties = {
        ["bluez5.enable-hw-volume"] = true,
        ["bluez5.roles"] = "[ a2dp_sink, headset_audio_gateway ]"
    }
}

May I remove bluez-alsa-git package if I use pipewire instead of alsa?

Re: [SOLVED]Alsa with external USB sound card and external USB bluetooth

Okay, I'm going to mark this topik as solved. Dont know which step solved but now I have a2dp profile for my bluettoth earplugs. So what I did:

1. Changed bluez.lua akkordin to this

#bluez_monitor = {
#    properties = {
#        ["bluez5.enable-hw-volume"] = true,
#        ["bluez5.roles"] = "[ a2dp_sink, headset_audio_gateway ]"
#    }
#}

 monitor.bluez.properties = {
   bluez5.enable-hw-volume = true
   bluez5.roles = [ a2dp_sink, headset_audio_gateway ]
 }

2. Solved "archlinux (uetoothd)[413]: bluetooth.service: ConfigurationDirectory 'bluetooth' already exists but the mode is different. (File system: 755 ConfigurationDirectoryMode: 555)" according to this

3. finally I removed bluez-alsa-git

Thanks to V1del for help!

Re: [SOLVED]Alsa with external USB sound card and external USB bluetooth

I have two more, not too important questions:
1. Is it possible to make change automatically between bluetooth, usb, and speaker (in this order)?
2. I founf that link file for bluealsa.service still exist even I removed bluez-alsa-git with yay -Rns.... 

[soosistvan@archlinux ~]$ ls -l /etc/systemd/system/bluetooth.target.wants/
total 0
lrwxrwxrwx 1 root root 40 Feb  6 09:13 bluealsa.service -> /usr/lib/systemd/system/bluealsa.service
lrwxrwxrwx 1 root root 41 May 27  2018 bluetooth.service -> /usr/lib/systemd/system/bluetooth.service
[soosistvan@archlinux ~]$ cat /etc/systemd/system/bluetooth.target.wants/bluealsa.service 
cat: /etc/systemd/system/bluetooth.target.wants/bluealsa.service: No such file or directory

Should I remove manually?

Re: [SOLVED]Alsa with external USB sound card and external USB bluetooth

Not sure how well the "order" part of that can be done, but what you can generally do is enable "module-switch-on-connect" which will switch to whichever "new" device you're connecting by creating an /etc/pipewire/pipewire-pulse.d/10-loadConnectModule.conf 

pulse.cmd = [
    { cmd = "load-module" args = "module-always-sink" flags = [ ] }
    { cmd = "load-module" args = "module-device-manager" flags = [ ] }
    { cmd = "load-module" args = "module-device-restore" flags = [ ] }
    { cmd = "load-module" args = "module-stream-restore" flags = [ ] }
    { cmd = "load-module" args = "module-switch-on-connect" }
]

As for the bluealsa leftover symlinks, yes you can just remove those.

Also for posterity's sake, since you're using pipewire now, get rid of the original asound.conf and install pipewire-alsa instead as you otherwise don't have proper integration should you encounter an application that's ALSA only (though those really aren't that widespread anymore)
