[Pkg-alsa-devel] Bug#814757: alsa-base: dmix/software mixing doesn't work

[Andoru]

> Sometimes pulseaudio is the cause.....

$ apt-cache policy pulseaudio
pulseaudio:
  Installed: (none)
  Candidate: 7.1-2
  Version table:
     7.1-2 500
        500 http://ftp.debian.org/debian unstable/main amd64 Packages

> According to http://alsa.opensrc.org/DmixPlugin you don't need to setup
dmix for analogue output. Dmix is enabled by default for soundcards which
don't support hardware mixing. You still need to set it up for digital
outputs.

If I don't set up dmix in the config file, it doesn't work either way.

> A better source for help is users at lists.debian.org as this was discussed
multiple times in the past.

Did they disable search engine indexing on those lists? I wasn't able to
find much useful info for ALSA and this specific issue while searching.
Also no posts over on those mailing lists turned up...

> A good start is just to throw away all the asoud.conf and .asoundrc
stuff. It overconstrains your system. The latest alsa is very tough and
should do what you need.

If I do that, I get no sound through the analog jack output. What probably
happens is that the HDMI is used for sound output instead... Somebody at
the ALSA user mailing list suggested me to use config #2 (from my first
message in this bug report) just to set the default soundcard without
setting dmix, but it didn't work...
