Actually in this setup also alsamixer fails, so I guess there is something not working at the WSL level (even if play works fine):

Actually I think this output are kind of expected. On WSLg, audio support is implemented at the PulseAudio level, not at at the kernel/ALSA level (see microsoft/WSL#5816 (comment) and the really nice https://github.com/microsoft/wslg/blob/main/README.md#wslg-architecture-overview, search for PulseAudio there). YARP uses PortAudio, and the build of portaudio on conda-forge (and also on apt, actually) do not compile the pulseaudio backend of portaudio, only the alsa backend (the apt version also the jack backend).

Actually I think this output are kind of expected. On WSLg, audio support is implemented at the PulseAudio level, not at at the kernel/ALSA level (see microsoft/WSL#5816 (comment) and the really nice https://github.com/microsoft/wslg/blob/main/README.md#wslg-architecture-overview, search for PulseAudio there). YARP uses PortAudio, and the build of portaudio on conda-forge (and also on apt, actually) do not compile the pulseaudio backend of portaudio, only the alsa backend (the apt version also the jack backend).

This is true, but it is important to understand a few things:

  • The alsa project mantains both the sound-related kernel drivers, and a userspace library called libasound
  • The pulseaudio project interacts with the alsa kernel driver, not with the userspace library libasound
  • In the alsa-plugins package, it is contained a package that permits to use libasound to actually access audio via pulseaudio, instead of accessing directly the alsa kernel modules

So, in a nutshell, if the pulseaudio backend of libasound worked correctly, we should be able to use programs that use libasound (as yarp does via portaudio) as long as libasound actually uses pulseaudio under the hood (even without enabling any pulseaudio backend of libportaudio, that indeed is not enable in the apt packaging.

This README explains quite well how the pulse backend for libasound works: https://github.com/alsa-project/alsa-plugins/blob/v1.2.12/doc/README-pulse .

Indeed, even in WSL2 if I run:

alsamixer -Dpulse

works fine, while simple alsamixer is failing, see:

Adding in ~/.asoundrc a file with content:

    pcm.pulse {
        type pulse
        fallback "sysdefault"
    }

    ctl.pulse {
        type pulse
        fallback "sysdefault"
    }

   pcm.!default "pulse"
   ctl.!default "pulse"

now amixer and alsamixer work out of the box.

And after adding that file, now yarpdev --device AudioPlayerWrapper --subdevice portaudioPlayer --name /icub/speakers --playback_network_buffer_size 0.5 --start --AUDIO_BASE::samples 4000 --AUDIO_BASE::channels 1 --dev_id 0 --AUDIO_BASE::rate 48000 starts without segfaulting, but I still need to try if it works (as there are a few errors):

I tested by playing a sound with:

yarpdev --device AudioRecorderWrapper --subdevice audioFromFileDevice --name /icub-virtualizer/microphone --min_samples_over_network 100 --max_samples_over_network 1000 --AUDIO_BASE::rate 16000 --AUDIO_BASE::samples 4000 --AUDIO_BASE::channels 1 --file_name file_example_WAV_1MG.wav

then:

yarp connect /icub-virtualizer/microphone/audio:o /icub/speakers/audio:i

and

yarp rpc /icub-virtualizer/microphone/rpc
> start

and not all the sound is actually playing, but something is played.
