Problem with ALSA lib under pipewire

Hello,
I am trying to start a program that supposedly uses ALSA for sound output, I am running pipewire with pipewire-alsa installed, but it shows me the following errors:

Re: Problem with ALSA lib under pipewire

You broke your ALSA config somehow. The only thing you actually need for a proper pipewire <-> ALSA bridge is the pipewire-alsa package.

Did you use some dotfile installer that might want to bend paths into .config or somesuch? What are your outputs for 

aplay -lL
printenv | grep ALSA
stat /etc/asound.conf ~/.asoundrc

post the content of the config files mentioned above should they exist.

If your ALSA config looks fine, your program might be the issue, what tool is this exactly?

Re: Problem with ALSA lib under pipewire

I also try an other way, with python this time and I get the same king of error at the init of PyAudio, but that still look like my sound configuration is wrong for ALSA with pipewire, even fi the little test program manage to get all installed hardware sound system on my pc.

Here the .soundrc I created to try to solve the issue, but honestly the hw are random because I does not know and find what they really represent:

pcm.!default{

    playback.pcm{
        type plug
        slave.pcm "hw:1,0"
    }
    capture.pcm{
        type plug
        slave.pcm "hw:0,0"
    }
}

# This set the default control options to use *hw* card #1
ctl.!default {
        type hw
        card 1
}

I found them with the help of from the command "arecord --verbose -f S16_LE -c 2 -d 5 -Dplug:default welcome.wav && aplay welcome.wav" and changing the value of hw:x,y, until the record and play worked with arecord and aplay default.

Re: Problem with ALSA lib under pipewire

Get rid of this config and install pipewire-alsa that's all you need to do. And then tell applications that use the ALSA API to use the 'default' device. This config you have now bypasses pipewire and you will not be able to have audio from ALSA applications and pipewire/pulse using applications at the same time. If you have software that's dead set on not using the 'default' device, that software is broken and needs to be fixed.

Re: Problem with ALSA lib under pipewire

I started getting the same error messages on startup from certain ALSA/PortAudio-based software (in my case, first noticed with Audacity) that I know was working fine on this machine just a few months ago.  Interestingly, I didn't have any problems playing audio with in most applications (including Chrome, Firefox, MPlayer, VLC, aplay, and just about any game I tried, native or under Steam Proton), KMix and pavucontrol continued to identify the right sources/sinks and to control my system properly, `aplay -l` and `arecord -l` seemed to list all devices properly (matching what I see in KMix/pavucontrol), and `pactl get-default-source` / `pactl get-default-sink` were both set to the correct device.  However, at some point my card numbering switched, so that my onboard audio is now card 1, device 0, while "card 0" is the device for sending sound over HDMI.  I'm 99% sure that this changed when I uninstalled the sof-firmware package about a month ago, but it could also be due to a kernel upgrade and/or the shift to alsa-lib version 1.2.14-1 (which looks like it got somewhat stricter about interpreting the config files).  Anyway, even though a lot of software had no trouble detecting and using card 1 as the default input and output device, it looks like other software (Audacity) was insisting on attempting to open card 0 first, and not gracefully falling back to other devices after receiving errors.  Anyway, I fixed it by creating ~/.asoundrc with the following contents:

defaults.pcm.!card 1
defaults.pcm.!device 0

pcm.dsp {
    type plug
        slave.pcm "dmix"
}

You will of course need to match the !card and !device lines to whatever `aplay -l` reports for the desired device on your system, but I have a feeling something similar will be helpful to anyone else getting the "Unable to open slave" / "Invalid card 'card'" messages.

Config notes for my system:
  * Although I mostly discuss ALSA above (since these errors are coming from the ALSA layer), I am indeed running Pipewire as my audio backend, with the pipewire-pulse and pipewire-alsa compatibility layers installed and wireplumber as my routing manager, which I think is the default Arch configuration these days.
  * I originally installed sof-firmware over two years ago to get sound output working over HDMI.  However, as the kernel drivers have advanced, this is no longer necessary, and I now get more consistent sound-over-HDMI performance without the Sound Open Firmware installed.  YMMV on different hardware, but it's definitely worth verifying the presence or absence of sof-firmware on your system, and either installing or uninstalling it as appropriate if you really can't get anything else to work.

Re: Problem with ALSA lib under pipewire

You  don't need nor want that asoundrc with pipewire-alsa in place, which  is all you need.  Get rid of it, and tell audacity to record from the pcm: default card, which will normally map to a pipewire-alsa backed ALSA device that gets handled via pipewire as the rest of the system.

Yes card order isn't stable which is why you can generally not rely on the numeric index. While this is irrelevant while properly using the pipewire-alsa plugin, the "correct" way of setting up a defaults card or device override is by either fixing the index order with modprobe config or not using indexes but the card names (what aplay -l shows directly after the index as the name. e.g. 

card 0: A50 [Astro A50], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

has the "name" A50 so one could also write 

defaults.pcm.!card "A50"

that is more guaranteed than the numerical index.

Re: Problem with ALSA lib under pipewire

The problem is that Audacity won't even start up when it's trying to use the wrong card; it spits out the error messages shown above and then segfaults.  That problem went away when I added the ~/.asoundrc, and all other aspects of audio on this system appear to still be working as expected, so I think it's worth trying for anyone else in a similar situation.

I completely agree that this is all a bunch of faff that ought to be unnecessary, and it's a poor reflection of the state of audio on Linux and the average user experience.  Pipewire is great internally, but it's not a solution to the layers of cruft and incompatible libraries that have built up over the last 30 years.  Since the reality is that alsa-lib and portaudio do not yet have graceful fallback behavior, the ~/.asoundrc suggestion is far more useful to a new user than just saying "that's not how it's supposed to work!"

The by-name matching is indeed an even better solution, and I'll try that next, but I still don't know of any way to get Audacity working on my setup on current Arch without /something/ in ~/.asoundrc when the desired card is not #0.

Re: Problem with ALSA lib under pipewire

hmm? That would be news. Assuming that it indeed randomly dies. What happens if you start it, and then explicitly check that pcm:default is selected? you should be able to get rid of that file, unless you're overriding it somewhere  else and you are just "logically papering" over it by adding a file earlier in the lookup precedence. Ftr this works fine here, audacity starts and plays via the default pcm and the only configuration that exists is the default device bendover that pipewire-alsa does, so this should definitely not be something your average user will notice.

Assuming your asoundrc is missing, what output do you get from 

aplay -lL
printenv | grep ALSA
stat /etc/asound.conf ~/.asoundrc
pactl list sinks

and the output while launching audacity? The only thing I see that could have a general bearing on this is if sof-firmware based cards do something incredibly weird when queried in which case creating such an .asoundrc might help, but it should™  not be necessary.

Re: Problem with ALSA lib under pipewire

I don't have an /etc/asound.conf or any environment variables containing "ALSA".  Audacity's error messages on startup without the .asoundrc are:

I don't think there's any problem accurately detecting the system hardware, it's just that some apps using the ALSA interface struggle to identify the right output.  When I add the ~/.asoundrc and am able to get into Audacity, the Preferences dialog has Interface Host: ALSA Using PortAudio, Playback Device: pipewire and Recording Device: pipewire, and MIDI Interface Host: ALSA Using: PortMidi.  mod-pcm (and all other modules except mod-script-pipe) is set to Enabled, but pcm: default is not an option for me in either the playback or recording device drop-down menus.  However, Audacity seems to be fully capable through the pipewire devices.

Re: Problem with ALSA lib under pipewire

Please wrap everything in [ code ] instead of [ quote ] when posting outputs

Thing is there's no reason you'd have to have that many dmix lookup issues assuming a properly working default setup. Something is off in an alsa config matter on your system that  that .asoundrc becomes necessary. what do you get from 

pacman -Qkk alsa-lib alsa-utils alsa-ucm-conf alsa-plugins
#This is going to be a load of output, but without your config present, make sure strace is installed and do a
strace -o /tmp/aplay.strace aplay -lL

Note that this is just somewhat curiosity on my side, I'm fairly knowledgeable on how the alsa lib loader works and what you're seeing should not be possible assuming a default Arch config with the only ALSA level adjustment coming from pipewire-alsa. Audacity works fine here without any custom shenanigans, but if you're fine with this solution I don't intend to stop you.

Re: Problem with ALSA lib under pipewire

I haven't modified anything about the system ALSA or Pipewire configuration, other than installing and later uninstalling sof-firmware, and eventually hitting on the ~/.asoundrc solution.

alsa-lib: 161 total files, 0 altered files
alsa-utils: 120 total files, 0 altered files
alsa-ucm-conf: 1008 total files, 0 altered files
alsa-plugins: 78 total files, 0 altered files

There weren't any tables or anything else that would benefit from a monospaced font; for most users, the proportional is more comfortable for reading long pieces of text.  Nevertheless, I'll use mono for the 1411 lines of strace output (I used grep to weed out the mmap()/mprotect()/ioctl() calls to eliminate another ~1000):

Re: Problem with ALSA lib under pipewire

It's more the scrollable box rather than the monospace font that makes code tags more useful for longer outputs.

Not seeing anything ultra obvious other than that the "correct" default hint for pipewire-alsa should™ include "Default ALSA Output (currently PipeWire Media Server)" so something must be resolved differently here.
