Re: [Alsa-user] How to record the mic and speaker at the same time?

[cong fu <fc...@gm...>]

Surely if I use a speaker I can get the background music route back from
mic. but there will be a very bad audio quality as i guess...
So I want  to use the headset and the mic, then there will be no music echo
after I record the "mic" and "speaker" together.

But how can I mix the mic and speaker together?
I want to use "~/.asoundrc" or "amixer" or something like that...
