Please provide mocp_server_log file in case when it's not working. You can generate it by running mocp -D first killing all mocp processes.

Can you compile run and paste the output of this program: http://users.daper.net/~daper/pub/oss_formats.c

Just download it and type make oss_formats.

Please try the following patch (applywith patch -p0 < file.patch:
ftp://ftp.daper.net/pub/soft/moc/patches/moc-2.4.2-2.5.0-alpha2-oss-vmix-fix-1.patch

This is not a real solution, but a workaround and should work.

Yes, it will be fixed in all future releases.

Software mixer isn't so difficult. What MOC displays now in the mixer place?

May be he display alsa mixer's, but i compile MOC without alsa support and uninstall alsa from system :) Or may be he cut this positions from config:

# OSS Mixer channel: pcm or master
OSSMixerChannel = pcm

# Second OSS Mixer channel: pcm or master
OSSMixerChannel2 = master

But with or without vmix mixer don't work in MOC+OSS.

It's not FIX in present!!! For me options "pcm" or "master" not correctly. In ossmix sound vol changes then i modify "headph" (output for headphones) and then i modify "vmix0-vol" (if i use vmix (software mixer for OSS)). Ossmix command output: http://paste.org.ru/?cqgh2k

Author, fix it please!
