/dev/mixer doesn't exist

I've been using OSS for quite a long time but I decided to switch back to ALSA. I uninstalled OSS and removed ALSA from the blacklist. However, this is what happens when I try to open alsamixer:

alsamixer 
ALSA lib ctl_oss.c:398:(_snd_ctl_oss_open) Cannot open device /dev/mixer
cannot open mixer: No such file or directory

Interestingly the sound still works - Youtube videos have sound, but nothing else does. mplayer for example says this:

[AO_ALSA] alsa-lib: pcm_oss.c:397:(_snd_pcm_oss_open) Cannot open device /dev/dsp

Any ideas?

Re: /dev/mixer doesn't exist

A couple of thoughts

Do you also have extra/alsa-oss installed? Are you loading that on startup?

You can select alsa with -ao switch in mplayer

mplayer -ao file.avi

See

mplayer -ao help

Re: /dev/mixer doesn't exist

OSS as in OSS4 or ALSA OSS emulation?

This looks like remnants of some weird "trick ALSA apps to use OSS" configuration. Alsamixer and mplayer's ALSA plugin should never touch /dev/dsp or /dev/mixer.

Are you sure you don't have some funky /etc/asoundrc or ~/.asoundrc installed?
