Generic x86_64 device : ALSA lib underrun occurred #106
Description
Hello everyone and thanks for all the work already and futurely done.
I use Libreelec 12.2.1 legacy on a generic AMD x86-64 (miniforum UM350 to be exact).
The Moonlight addon install and start without apparent error, the video and controls works perfectly but the sound works randomly for about 1/10th of a second at a time.
My only clue at this point is this line repeating indefinitely in the moonlight-qt.log of the addon when the streaming is on :
ALSA lib /build/build.LibreELEC-Generic-legacy.x86_64-12.2.1/build/alsa-lib-1.2.11/src/pcm/pcm.c:8740:(snd_pcm_recover) underrun occurred
Note that in Kodi, while everything works fine in playback, the UI sound does not work.
Another Moonlight client (Xbox One) works perfectly as well so no problem from Sunshine I reckon.
Thanks for any help anybody may provide.

New informations:
Interesting line in dmesg
I guess C0D0 stand for card 0 device 0.
But the correct one should be card 0 device 3 if I understand a play - l

Have you tried explicitly configuring your audio device in Kodi, so not selecting the "default" audio device?

Hello !
I'm on Libreelec 12.2.1 and there isn't a "default" option, there's several ALSA output device for HDMI, 1 for analog, 1 for S/PDIF and a last PULSE device for Bluetooth. The first output recognize my AV receiver and is the only one that get me sound. I already have tried to switch several times so even if it was a "default" selection, it have been unselected and selected again.
Remember that I actually kind of have sound in Moonlight, but at a rate of a fraction of second every few second.
