Trying to use sound card

isaac.dvorz · 07-28-2015, 01:32 AM

Hello,

I'm using Debian and trying to use my sound card via putty (so I can later stream with VLC)
I'm using Pianobar for example to try and play pandora, here are the errors I'm getting

Code:

ALSA lib confmisc.c:768:(parse_card) cannot find card '0'
ALSA lib conf.c:4241:(_snd_config_evaluate) function snd_func_card_driver returned error: No such file or directory
ALSA lib confmisc.c:392:(snd_func_concat) error evaluating strings
ALSA lib conf.c:4241:(_snd_config_evaluate) function snd_func_concat returned error: No such file or directory
ALSA lib confmisc.c:1251:(snd_func_refer) error evaluating name
ALSA lib conf.c:4241:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory
ALSA lib conf.c:4720:(snd_config_expand) Evaluate error: No such file or directory
ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM front

The VLC command I'm later intending to use is:

vlc -vvv alsa://hw:1,0 --sout '#rtp{dst=192.168.1.150,port=1234,sdp=rtsp://192.168.1.150:8080/test.sdp}'

Some info on the system:

Does the sound work with the normal system?

isaac.dvorz · 07-28-2015, 04:59 AM

I tried to plug-in headphones but I didn't hear anything. Its a server so It not connected to a screen for further testing .

isaac.dvorz · 07-29-2015, 02:31 AM

I finally managed (don't know how) to get the sound to work when I plug headphone directly to the computer.
The VLC streaming that I'm trying to accomplish doesn't work, I think I need to set something like the windows steromix but don't know how.

Sound is muted by default so check alsamixer. The cannot find card 0 is concerning. Maybe the user is not in the audio group? Otherwise it should mostly work. If you want to point at card 1 instead of card 0 (default) that takes some configuration or pulseaudio.

.asoundrc

Code:

defaults.ctl.card 1
defaults.pcm.card 1
defaults.pcm.device 0

debian uses pulse audio now

isaac.dvorz · 07-31-2015, 12:19 AM

Hi,
the sound does work now, but I can't get it to stream like I'm doing "Stereomix" in windows.

Shadow_7 · 07-31-2015, 04:22 PM

You need pulseaudio to stream the audio across a network. Which you actually need locally if you have more than one user accessing the audio through pulse. At least on debian 8 with a pulse over jackd configuration.

~/.config/pulse/client.conf

Code:

default-server = 127.0.0.1

/etc/pulse/default.pa

Code:

load-module module-native-protocol-tcp auth-ip-acl=127.0.0.1

~/.asoundrc

Code:

pcm.pulse {  type pulse  }
ctl.pulse {  type pulse  }
pcm.!default {  type pulse  }
ctl.!default {  type pulse  }

You don't need the first two if your the user who started pulseaudio.

how do I connect in windows to that using vlc?

Shadow_7 · 08-03-2015, 05:45 AM

I don't know. But changing localhost aka 127.0.0.1 to a public IP might be a good first attempt.
