frequent popping/crackling with pipewire

I recently installed pipewire and pipewire-pulse and removed pulseaudio and I've been noticing lots of popping and crackling, even with nothing going on on the machine, just spotify, firefox, etc.

Logs for pipewire say:

And so on; I can see using

pw-top

that the popping corresponds to these errors in these processes. 

Do I need to adjust the audio buffer size or something to get playback that doesn't pop?  Or is pipewire just not ready for audio yet and I should go back to pulse?  My pipewire.conf has the default, commented out settings:

    #default.clock.quantum =		1024
    #default.clock.min-quantum =	32
    #default.clock.max-quantum =	8192

Re: frequent popping/crackling with pipewire

I just tried pipewire first time today since pulseeffects 5.0.0 was released on arch which now requires pipewire.

I too has crackling/popping but also very large delays.

default.clock.quantum = 32
default.clock.min-quantum = 32
default.clock.max-quantum = 768

delays are gone now but crackling/popping still there but massively reduced

Re: frequent popping/crackling with pipewire

I recently switched to pipewire as well for the same reasons sinatosk mentioned.

I changed my pipewire.conf like sinatosk suggested and the crackling and delays are gone for me.

Re: frequent popping/crackling with pipewire

Hi, I also have this issue. It's fine on my laptop speakers, but when connecting a Focusrite Scarlett 2i2, the crackling sounds are terrible.

Just tried this, and now there's no audio output at all, and music players seem to play songs much slower than usual (one second taking five).

I ran

pw-cli i 0

and got:

        id: 0
        permissions: rwxm
        type: PipeWire:Interface:Core/3
        cookie: 671024961

        version: "0.3.20"
        name: "pipewire-0"
*       properties:
*               core.name = "pipewire-0"
*               context.profile.modules = "none"
*               core.daemon = "true"
*               link.max-buffers = "16"
*               default.clock.quantum = "32"
*               default.clock.min-quantum = "32"
*               default.clock.max-quantum = "768"
*               default.clock.rate = "48000"
*               default.video.width = "640"
*               default.video.height = "480"
*               default.video.rate.num = "25"
*               default.video.rate.denom = "1"
*               mem.allow-mlock = "true"
*               cpu.max-align = "32"
*               object.id = "0"

Any ideas?

Re: frequent popping/crackling with pipewire

I'm assuming you set it in "/etc/pipewire/pipewire.conf"?

Maybe your machine not powerful enough. The lower the numbers, the more demanding

Try higher numbers

This was definitely the problem, I set it to

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

I don't know if these are "correct" numbers in accordance to audio standards, but it works flawlessly for me.

Thanks!

Edit: My laptop is running an i5-6300U @ 2.40GHz

Re: frequent popping/crackling with pipewire

on my laptop I originally used which has ryzen 5 3500U

default.clock.quantum = 256
default.clock.min-quantum = 256
default.clock.max-quantum = 768

then changed it too

default.clock.quantum = 32
default.clock.min-quantum = 32
default.clock.max-quantum = 768

and desktop which has a ryzen 9 3950X

default.clock.quantum = 32
default.clock.min-quantum = 32
default.clock.max-quantum = 32
