Is there a guide somewhere on how to use the pi sound system? It would be good to have something definitive as there is lots of stuff out there that contradicts, and it is not like I want to do anything out of the ordinary.
I have two usb microphones, both appear in under the speaker menu on the top right hand corner of the screen, and yes I have maxed the volume in the device settings there. if I do
arecord -d 5 -f S16_LE test.wav then,
aplay test.wav I can hardly hear the recording using either microphone. It is recording - I can hear it. The play back is, I assume, fine as I can listen to things on the web.
After several hours surfing I get the impression one cannot set the record volume and there is a problem with my hardware??? A pi4 running buster.
Any help greatly appreciated, P
