HP Chromebook - snd_pcm_open failed: Device or resource busy <SOLVED>

[dcung]

On my HP Chromebook (with Mr.Chromebox BIOS) and @rcrsn51 script (myalsaucm.sh), I noticed that I can only get sound while using one app at a time.

Say if I am watching a youtube video on a browser tab - paused it, then opening another tab to watch another video, will not have sound without closing the previous tab.

Or if (without closing other paused app with sound) I use a video/music player then you get
ALSA error: snd_pcm_open failed: Device or resource busy

I found this, probably similar to what's described here (?).
https://comp.os.linux.hardware.narkive. ... ource-busy
which mentioned that you need to install a mixer.
But in this build (Boookworm LXQT), I have both AlsaMixer (works) and AlsaMixerGui (not working).

It's not a big deal now that I know the behaviour.
Just curious if there's some trick to 'improve' it.
i..e. no need to close paused app.

I did that.... and... problem solved.

I can run more than one app that use sound now...

Thanks @rcrsn51
