I have a Raspberry Pi 4 and have been messing around with Pulseaudio and Alsa a lot lately. I wrote an asoundrc file which I want the system to run every time it's on. However, Pulseaudio keeps deleting it and I haven't been able to find a workaround online. My initial idea was to write a python script to manually enter my code into the asoundrc file every time the Pi boots up. But I'm unsure how to go about this and maybe there is a better solution that I missed. So any suggestions would be really appreciated :)
Here is my current asoundrc file...
pcm.bth-1 { type plug slave.pcm { type bluealsa device "FA:D8:78:FB:57:36" profile "a2dp" } } pcm.bth-2 { type plug slave.pcm { type bluealsa device "5C:44:3E:54:E0:01" profile "a2dp" } } pcm.bth-multi { type plug; slave.pcm { type multi; slaves.a.pcm "bth-1"; slaves.a.channels 2; slaves.b.pcm "bth-2"; slaves.b.channels 2; bindings.0 { slave a; channel 0; } bindings.1 { slave a; channel 1; } bindings.2 { slave b; channel 0; } bindings.3 { slave b; channel 1; } master 1 } ttable.0.0 1 ttable.1.1 1 ttable.0.2 1 ttable.1.3 1 }
