No audio on Porteus installation

Recently installed Porteus on a USB stick with Unetbootin, and got my favourite apps installed and porteus.cfg pointed to an ext3 partition. So far liking the distro quite well :)

However, audio does not seem to work.

Output of "speaker-test":

Code: Select all

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 pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave
Playback open error: -2,No such file or directory
and output of "lsmod | grep snd":

Code: Select all

snd_hda_codec_hdmi     26628  1 
snd_hda_codec_realtek    42800  1 
snd_hda_codec_generic    33008  1 snd_hda_codec_realtek

firmware_class          4664  6 iwlwifi,btusb,r8169,drm_kms_helper,snd_hda_intel,iwlmvm
What can I do to resolve the problem?

Thanks, tome -- I got the sound working with the suggested changes in /etc/asound.conf. :Yahoo!:
