MPD and ALSA. (Solved)

First, I'm out of ideas, dunno why this happens.

While trying to play a song through an MPD client (ncmpc):

ALSA lib pcm_hw.c:1355:(_snd_pcm_hw_open) Invalid value for card
Error opening alsa device "hw:0,0": No such device

Device in mpd.conf:

audio_output {
        type            "alsa"
        name            "ALSA device"
        device          "hw:0,0"
        format          "44100:16:2"
}

Facts:

I have two cards in the machine. One SBLive 5.1 and one oboard. I don't use the onboard card, so the modules are not loaded. I'm not using the mpd package, i use the mpd-svn package von AUR, with the normal mpd package happens the same.

I'm grateful for all answers!

I remember that I had to comment out the device entry to get dmix working, but that might not be related (and it was for mpd from [extra]).

Yeah, but this configuration worked yesterday in CRUX, the same smile I think it's an ALSA related problem.  8)

When commenting out the device, the errors gonna crazier smile

Re: MPD and ALSA. (Solved)

I'm using the regular mpd (0.11.5-6), but this is all I have in mpd.conf as far as audio devices are concerned:

# Software Mixer
mixer_type              "software"
# ALSA Audio Output
ao_driver               "alsa09"

I used to use a SB Live and don't recall needing to anything special for mpd to work with it.
