Run:


cat /proc/asound/card0/codec#* | grep Codec

Result:



Codec: Realtek ALC269
Codec: Intel G45 DEVCTG



Can someone explain to me,why there are to codecs for one audio device?

My audio device:


00:1b.0 Audio device [0403]: Intel Corporation 82801I (ICH9 Family) HD Audio Controller [8086:293e] (rev 03)

The Realtek is for your analog, the second for digital/hdmi. The aplay -l command will show the
devices alsa sees.
