[alsa-devel] SALSA library and recording

Hi All, I am using salsa library to capture the data from the sound card. The requirement is that the recording should be done from line-in port of the sound card. The selection of "Line-in" port should be done programatically.

With ALSA library, I am able to select the line-in by calling snd_mixer_selem_set_capture_switch_all() function. However, this function is returning an error when SALSA library is used. Is there any other function/way to select the line-in mixer element in the SALSA API?

The help would be appreciated. Thanks & regards, manisha
