USB DAC isn't recognized (SONY UDA-1) #496

Hi all,

I'm working with a SONY UDA-1 connected via USB. I've tried power cycling the pi but I'm still getting audio through the stereo headphone jack.

Anything I can do to force USB audio?

Thanks!

I don't have that DAC but I had this problem getting my Focusrite Scarlett 2i4 to work over USB.

This solution worked for me: https://github.com/balenalabs/balena-sound/issues/314#issuecomment-715248194 @cpwood

FWIW, I was able to workaround this temporarily by getting an SSH session in the audio service and issuing the following commands:

pactl list

to find the name of the sink for my USB DAC, and then using that name:

pactl set-default-sink alsa_output.usb-soundcard-1.analog-stereo

I actually was able to set Device Variable (in balena dashboard) AUDIO_OUTPUT = alsa_output.usb-soundcard-0.analog-surround-40 (the sink I found from pactl list).

I theorize that I had this problem (even on the latest balenaSound) because the Scarlett 2i4 has 4 outputs - thus making it 'surround' rather than 'stereo'. Maybe the Sony has multiple outputs too?

Do I need to install pulseaudio?


root@balena:~# pactl list
bash: pactl: command not found

Slash how do you even install stuffz on the balena via cli? A goog of "balena package manager" doesn't turn up much useful.

Also, would would I just add "AUDIO_OUTPUT" or would I need "BALENA_HOST_CONFIG_AUDIO_OUTPUT"?

You have to be in the audio container - you will find pactl there.

buzuddha commented 3 years ago

Hmmm from the audio container pactl list | grep usb doesn't produce any result, even after rebooting the pi with the dac plugged in and turned on. pactl list gives: http://ix.io/3AyD

From the OS root lsusb gives 

Bus 002 Device 001: ID 1d6b:0003  
Bus 001 Device 001: ID 1d6b:0002

dmesg gives: http://ix.io/3AyB methinks this line might be relevant usb usb1-port1: unable to enumerate USB device usb-devices gives: http://ix.io/3AyC

Any thoughts?

Was going crazy, this worked for me as well with my own USB device after looking up the value with pactl. Thanks!
