How to record sound from 'pc'?

[ink3]

I need record some sound from pc (for exemple www - myspace).
I find that I do this with

Code: Select all

arecord -f cd record-file

arecord save file, but no sound.

I think that problem is my sound card or I need more soft.

Code: Select all

# lspci | grep -i audio
00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 01)

You probably need to activate a capture source. Open alsamixer, change to capture view (F4) and see if something is activated.

No, I try all options mic, front mic, cd, line

Meantime I find other solution. My card don't use stereo mix probably .
Then I use virtual alsa driver (alsa loopback driver)
Load module:

Code: Select all

modprobe snd-aloop

Create default file which use by alsa

Code: Select all

mcedit ~/.asoundrc

pcm.!default {
type hw
card 1
device 0
}

Run some music from myspace (we will not listen)
And I record:

Code: Select all

arecord -D hw:1,1 -f cd some_file

Or conversion on the fly:

Code: Select all

arecord -D hw:1,1 -f cd | lame -h - some_file.mp3

I managed to check whether in moc.

If you want to return to the initial settings,
change name .asoundrc or delete.

I think that this solution suitable to salix wiki
