OSS configuration on Dell Latitude D6320

[Gereon Kaiping]

Dear Multimedia ,

I'm trying to get skype to work under FreeBSD-9 on my Dell Latitude
D6320 laptop. The last problem I have is using the builtin microphone,
which is supposedly somehow connected to the webcam, so to make sure I
installed multimedia/webcamd. I use OSS as my sound system.

I can use microphone and speakers under audacity if I set the playback
device to /dev/dsp, but the recording device to /dev/dsp1. How do I
configure OSS to use these settings by default unless an application
explicitly demands something else? In skype, I cannot select a
specific sound device, just "oss" or "default" or "hdmi", and if those
in- and outputs work, they sound like a reasonable default anyway.

In case it helps, in particular if someone later needs to stumble upon
this because they have a similar problem:
