Roon Bridge on RPI4b and Tiny Core Linux

I think he wants to get sound from another output? Disabling alsa core, not just the specific alsa modules, would disable all sound.

Yes, I want to keep only USB output in ALSA, and disable built-in and hdmi audio

Easiest to do that in the rpi config.txt

removing the line

Code: [Select]

dtparam=audio=on
should take care of it.

It seems it apply to Raspberry OS, not to Tiny Linux - I can't find any config.txt in tiny core installation

To edit the file you need to mount the boot msdos part. of the boot media, like this if you use sdcard.

Code: (bash) [Select]

mount /mnt/mmcblk0p1/
vi /mnt/mmcblk0p1/config.txt

If you have nano installed it's little easier editor to handle the file.

Code: (bash) [Select]

nano /mnt/mmcblk0p1/config.txt

It works now for internal audio, but the HDMI remains enabled...
