[Alsa-user] Forcing asound.conf routing for OSS kernel drivers

[Johannes B. <dfn...@gm...>]

Hello list,

upon fiddling with my ALSA config and through the conversation with Adam
Nielsen I encountered that when using the OSS kernel driver emulation
for ALSA (i.e. not the userland "aoss" emulation) the profile which is
stored in /etc/asound.conf is ignored.

This seems logical, as kernel access to the filesystem is kind of hard
to realize. However, when looking into a recent kernel (2.6.23.13)
config, there is the following option present:

CONFIG_SND_PCM_OSS_PLUGINS: OSS PCM (digital audio) API - Include plugin
system

which yields the following description:

> If you disable this option, the ALSA's OSS PCM API will not support conversion of channels, formats and rates. It will behave like most of new OSS/Free drivers in 2.4/2.6 kernels.

However, on my system - although I have this option activated - OSS
ignores the asound.conf files. Is there some magic to it to make it work?

Greetings,
Johannes
