Re: [Discuss-gnuradio] audio_alsa_sink problem

[davek]

The grc dialtone flowgraph py would work ONLY if i changed BOTH

self.audio_sink_0 = audio.sink(44100, "hw:0,0", True)
to
self.audio_sink_0 = audio.sink(32000, "plughw:0,0", True)

and

self.samp_rate = samp_rate = 44100
to
self.samp_rate = samp_rate = 32000

not sure what to make of that...
looks like I was stumbling on 2 different things, device name syntax
and sample rate ( hardware limitation ? ) not sure...
