Music On Hold from Mic/Line In too slow

Hi there!

I would like to set my USB sound card’s input as the source for the Music On Hold in FreePBX. I am using a sound card plugged into the USB port of my Raspberry. I do get some sound to the MOH by using the following command:

/usr/bin/arecord -q -f S16_LE -r 8000 -c 1 -D hw:2,0

However the sound on the MOH sounds like it is being played back at a wrong speed. It is far too slow. Someone suggested that I might try and use the sox command instead and set the output rate to a different value? Apparently you cannot do that with the arecord command? I do not how to do that though. :frowning:

My question:

How do I get the sound from my LINE IN to be played at the right speed as MOH? Can anyone help with the sox command? Any other ideas?
