[SOLVED] Problems with USB soundcard in HP ProLiant gen8

[valhala]

Hi everyone!

I have a USB sound-card that alsaplayer recognizes:

Code: Select all

root@gnulinux:~# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 1: Device [USB Audio Device], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

But when I try to play a MP3 or WAV audio formats displays a error like that:

Code: Select all

root@gnulinux:~# aplay music.mp3 
ALSA lib confmisc.c:768:(parse_card) cannot find card '0'
ALSA lib conf.c:4259:(_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:4259:(_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:4259:(_snd_config_evaluate) function snd_func_refer returned error:No such file or directory
ALSA lib conf.c:4738:(snd_config_expand) Evaluate error: No such file or directory
ALSA lib pcm.c:2239:(snd_pcm_open_noupdate) Unknown PCM default
aplay: main:722: audio open error: No such file or directory

And similar error its going on when I try to do a speaker-test:

Code: Select all

root@gnulinux:~#  speaker-test 

speaker-test 1.0.28

Playback device is default
Stream parameters are 48000Hz, S16_LE, 1 channels
Using 16 octaves of pink noise
ALSA lib confmisc.c:768:(parse_card) cannot find card '0'
ALSA lib conf.c:4259:(_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:4259:(_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:4259:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory
ALSA lib conf.c:4738:(snd_config_expand) Evaluate error: No such file or directory
ALSA lib pcm.c:2239:(snd_pcm_open_noupdate) Unknown PCM default
Playback open error: -2,No such file or directory

I supposed that the problem is that somewhere is defined the sound-card by default the card '0' and in my configuration it seems to be that the USB card is the card '1'.

Can anybody help me?

Either install PulseAudio and use pavucontrol to set the default output device or modify your system configuration files to allow ALSA to do this without PulseAudio:

I followed the tutorial of ALSA without PulseAudio, specifically I used the "Alternative method" and It works perfectly.

Thank you!
