Please set this in your kernel:

CONFIG_SND_PCM_OSS:
To enable OSS digital audio (PCM) emulation (/dev/dsp*), say Y
here and read <file:Documentation/sound/alsa/OSS-Emulation.txt>.
Many programs still use the OSS API, so say Y.

Location: -> Device Drivers -> Sound card support (SOUND [=y]) -> Advanced Linux Sound Architecture (SND [=y])

Yes, k4guitune is using OSS instead of ALSA.   And I'm reclutant in adding linux-info.eclass based config check for CONFIG_SND_PCM_OSS because far as I know you might as well be compiling alsa-drivers outside of kernel itself which would just return false positive.

So... Feel free to close this as WORKSFORME after enabling OSS in kernel and testing it works.

Comment 3 Stephan Litterst 2010-04-17 16:48:37 UTC

Yes, it works!
Enabling OSS-emulation in the ALSA-section of the kernel did the job.
(Enabling the old depreceated oss in the kernel was the wrong way I did before...)
