[SOLVED] Some ALSA problems, sound only with VLC Player

Hi all together,

after trying to get ALSA working almost the whole day I think I have to ask you for help.

My Problem is the following:
The only sound output I can hear at the moment is the output of VLC Player, my other applications (that I'm aware of) are all quiet (e.g. Firefox (HTML5/FlashPlayer), TeamSpeak, Audacity, Sauerbraten, WarThunder, aplay) it doesn't matter whether VLC Player is running or not or what program is started first.
Additionally my microphone works in TeamSpeak and Audacity, but not with arecord.

VLC's ouput module is set to 'Automatic'.

Different Outputs:

aplay test.wav

ALSA lib pcm_dmix.c:1024:(snd_pcm_dmix_open) unable to open slave
aplay: main:722: audio open error: No such file or directory

-

speaker-test -c 2

speaker-test 1.0.29
Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
ALSA lib pcm_dmix.c:1024:(snd_pcm_dmix_open) unable to open slave
Playback open error: -2 No such file or directory

-

arecord -d 5 test_mic.wav

ALSA lib pcm_dsnoop.c:614:(snd_pcm_dsnoop_open) unable to open slave
arecord: main:722: audio open error: No such file or directory

My /etc/asound.conf only contains a few commented lines I created while trying to get it work:

#pcm.dmixer {
#	type dmix
#	ipc_key 1024
#	ipc_key_add_uid 0
#	ipc_perm 0660
#}
#pcm.dsp {
#	type plug
#	slave.pcm "dmix"
#}
#pcm.!default {
#	type plug
#	card PCM
#	slave.pcm "dmix"
#}

-

cat /etc/modprobe.d/alsa-base.conf

options snd-hda-intel index=1,0

This was necessary to get my microphone working, see https://bbs.archlinux.org/viewtopic.php?id=187031

I hope you can help me, especially as I'm still new to archlinux and pretty confused by ALSA.

Re: [SOLVED] Some ALSA problems, sound only with VLC Player

I repeated some of the stepsI already did yesterday, now everything (as faras I see it) works.

What I did:
Delete the contents of /etc/modules, /etc/modprobe.d/alsa-base.conf and /etc/asound.conf.
Followed these steps to remove the saved ALSA settings.

As I said that's the same I did yesterday, I also rebooted a couple of times, but today it works, don't ask me why.

Thanks anyways
