How to get "Mix" device?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

I'm trying to record audio playing on the computer. I followed the
instructions at
http://www.audacityteam.org/wiki/index.php?title=Recording_audio_playing_on_the_computer .
I run AlsaMixer (v1.0.16), switched to the view "Capture" and stuck: the
only devices are "Capture", "Digital" and "Input Source".

But there is no device "Mix".

Why it could be so? Should I add some option somewhere to get "Mix"?
Any ideas are welcome!

Card: HDA Intel
Chip (as said by AlsaMixer): SigmaTel STAC9227
Linux kernel version: 2.6.18
Alsa version: 1.0.14

There are no options in modules.conf. I load the sound modules manually:

# modprobe snd-hda-intel
# modprobe snd_pcm_oss
# modprobe snd_seq_oss

Somehow automatically, other sound modules are also loaded:

snd_seq_dummy           8196  0 
snd_seq_oss            38656  0 
snd_seq_midi_event     11520  1 snd_seq_oss
snd_seq                56784  5 snd_seq_dummy,snd_seq_oss,\
  snd_seq_midi_event
snd_seq_device         12556  3 snd_seq_dummy,snd_seq_oss,snd_seq
snd_pcm_oss            47008  0 
snd_mixer_oss          21120  3 snd_pcm_oss
snd_hda_intel         266524  3 
snd_pcm                81540  2 snd_pcm_oss,snd_hda_intel
snd_timer              26116  2 snd_seq,snd_pcm
snd                    59112  11 snd_seq_dummy,snd_seq_oss,\
  snd_seq,snd_seq_device,snd_pcm_oss,snd_mixer_oss,\
  snd_hda_intel,snd_pcm,snd_timer
soundcore              13792  3 snd
snd_page_alloc         14088  2 snd_hda_intel,snd_pcm
