Re: [Discuss-gnuradio] Problem with making sound card as source

[2 1]

Thanks Breett:) I've solved this problem by turn on capture item in the
mixer. And I guess that's why there are many people say that there
linux cannot recording sound.

I had a similar problem- turned out not to be the hardware.
Run alsamixer and make sure to turn on capture on your line input (with
spacebar) and turn up the volume all the way, then turn on capture on
capture and turn the volume up all the way again. You should then be
getting audio and adjust the volume down to reduce clipping.
