mpd stopped working

bagondo
Hi everybody,
I recently installed linux voyage + mpd version 0.10.0, with mpd ver.0.19.9,
and it WAS working quite well.
I'm using a Yulong DAC in "bit perfect" mode, with ALSA, my system is an old
Centrino-powered Acer Travelmate 663 LMi with 1GB RAM.
Everything was fine until I shutdown the OS with "shutdown -h now", while a
song was playing.
The next time I started the system (I can't remember if the DAC was already
on), the last song I was playing suddenly came out from the
laptop's embedded Realtek audio card.
Then, I remember, I made sure the DAC was on and rebooted: same result, as
soon as the OS was loaded, music started coming out from the Realtek.
Worse than that, I couldn't even connect with any client to STOP the sound,
which was coming out at the loudest volume.
I then googled a little, and found the "mpd.conf" parameter "restore_paused
"yes"" so, at least, I managed to restart without that song banging
my brain. After some hours I found out that I couldn't connect from a client
because the IP address was DHCP-assigned, and it had changed because
of my son's new cell phone had "stolen" my usual IP address. Anyway, I set
the IP as static, eventually managed to connect from a client...but now...
no sound at all!!! The DAC is not receiving any signal.

I checked ALSA with both
[code]aplay -vv /path/to/file.wav[/code]
and
[code]speaker-test -c 2 -t wav[/code]
the sound is played through the DAC, so I think it might be a problem with mpd.
