Hello,
I am currently building an app using electron. But the problem is when I installed the snap version of it without using the --devmode flag it will have no sound and print some logs:
ALSA lib conf.c:3916:(snd_config_update_r) Cannot access file /usr/share/alsa/alsa.conf
ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) Unknown PCM default
ALSA lib conf.c:3916:(snd_config_update_r) Cannot access file /usr/share/alsa/alsa.conf

here’s my original snapcraft.yaml configuration:

Here’s the link of the app I built https://github.com/roldanjrCodeArts9711/productivity-timer.
) Can you help me with commands to fix alsa cannot access?
