Input but not output in pulseaudio

Hello everybody,

I'm trying to figure out a Pulseaudio issue.
When I connect my digital piano to the USB port, I can see the input sound in Pulseaudio, but I get no output.
I tried all the output pull down menus and all the possible configurations and got nothing.
If I record (using arecord) I can see the signal in the record page, and the recording is fine, but I still cannot hear any output.
If I play back the recording, the output is fine.

Any tips on how to figure this out?

Start by examining the available sources and sinks

Code:

pactl list sinks

Code:

pactl list sources

You'll need to load the looback module first

Code:

pactl load-module module-loopback latency_msec=1

then use pavucontrol to select the desired source (Recording tab) and sink (Playback tab)

This can also be done via the pactl command itself eg

Code:

pactl load-module module-loopback latency_msec=1 source=1 sink=0

BTW, you can make it permanent by adding the required user configuration in ~/.pulse/default.pa

Glad to have been of guidance!
