a few months ago i often uses arecord to show a vu-meter of a sound input of an externen usb sound card.
Yesterday i wanted to do the same by use the command:
But it doesn't really show the vu-meter. Please have a look on the attached screenshot (sorry for the bad resolution).
Code: Select all
arecord -vv -D plughw:1,0
Does somebody know something about this issue?
BTW: the external soundcard is a Behringer UCA 202.
