fix the vmix.pcm for a specific app

[Chipster]

Hello

Actually i'd like to know if it's possible to fix the vmix.pcm for a app, in a way that everytime this app starts, the volume settings stay configured and everytime this app stop, the volume settings reset

1. You can use a shell script and ossmix for this. Something like

Code: Select all

#!/bin/sh
app arguments
ossmix app volumes

ossmix can accept an app name for a volume argument**, so this should work.

** If the app uses multiple engines [vmix.pcms] it'd be problematic - but I haven't yet seen an app which does it.

2. I sent a patch to oss-devel which let ossxmix do exactly this, but it was rejected. If you're willing to recompile ossxmix this could do this (minus: it involves constant polling of the mixer).

Hello. Thx for your help. I try with a shell script before
There is mumble who use 2 PCM and i use it :/

Why it was rejected ?

I see. It uses one for output and another for input. I have an idea...

As for the rejection, the devs didn't want a userland program to do this (except I can't see at all how to do it otherwise). You can search oss-devel and find the thread.
