Pulseaudio on container

[jhay06]

Hello would like to ask , how can i connect lima containers to default mac os audio so i can use pulseaudio on the container.
i am developing ubuntu touch apps using lima can't run desktop mode because it looks for pulse audio . then when i install pulseaudio it still error i think because pulseaudio is not routed to sound driver from mac .

I don't think there is any sound support in the default setup, so it would have to be added as an option first.

$ qemu-system-x86_64 -soundhw help
Valid sound card names (comma separated):
sb16        Creative Sound Blaster 16

pcspk       PC speaker

-soundhw all will enable all of the above

There is a newer -audiodev flag. Then setting up pulseaudio is a headache all by itself, once the device is there.

I believe you want the "coreaudio" output device, for Mac ?

-device intel-hda -device hda-output,audiodev=coreaudio

Then once you have audio working in the VM, you need to map all the required volumes (for PA) into the container.

hi thanks for the reply , but where is the stored config of the qemu created by lima ?

[afbjorklund]

It's not really stored (as far as I know?), but for testing you could just use ps

I was thinking it could eventually using something like audio: in the YAML...

Maybe open a GitHub issue for it ?

[jandubois]

For testing you could try:

QEMU_SYSTEM_X86_64="qemu-system-x86_64 -device intel-hda -device hda-output,audiodev=coreaudio" limactl start

Then check if the audio device has been created, and try to setup PA.

If this works, then we can discuss providing an option to configure this, or add it by default (if the cost to do so is low).
