Hi Manisha,
Sorry this is not a response which will help you.
I am facing similar issue. I am using SALSA and I am trying to record from a USB headset. The USB headset does have a mixer elem "Mic". But when I use snd_mixer_selem_get_capture_dB_range() or snd_mixer_selem_get_capture_volume_range() I just get zeroes.
I did not do any set() functions like snd_mixer_selem_set_capture_switch_all(). Do I need to do that ? What is your source of info about how to set up the mixer for capture ?
Thanks in advance

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
