try this:
“cat /proc/asound/devices”

It’s different depending on your setup but here it is on this computer:

bash-3.1$ cat /proc/asound/devices
2: : timer
3: : sequencer
4: [ 0- 4]: digital audio playback
5: [ 0- 3]: digital audio capture
6: [ 0- 2]: digital audio capture
7: [ 0- 1]: digital audio capture
8: [ 0- 0]: digital audio playback
9: [ 0- 0]: digital audio capture
10: [ 0] : control

I only have the built-in sound device on this PC and it is lited above
as “card 0”. Look in /proc/asound under card0 directory for more
details.

Hello people …

I tried specifying pcm1c listed in card 0 folder which said its a mic
…but it gives an error that the device is not found . The program
audio_to_file only works with hw:0 specified …
What exactly is hw:0 ? i.e what’s the audio that is considered ? Here is
it possible to give audio through the mic in real time?

Any response people?

Thanks & Regards,
Poornashree
