I’m having trouble getting the audio sink to work well with
pulseaudio and a USB soundcard. It seems the gnuradio audio sink
throws the packet away before the usb card has a chance to become
ready. This results in a race condition and a stuttering output with
audio underruns. Switching virtual consoles from one to the other
using ctrl+alt+fkey allows the program to function normally, as
long as the stream is not interrupted.
Making the buffer values accessable should fix this issue.
