grpc streaming example crashes and hangs #515
Description
Just cloned the latest repo for grpc -
running this on Raspbian (Raspberry Pi)
Cannot even break out of the program at all.
The sample rate of my usb mic is limited to 44100 and 48000. I tried changing those in the example but I get the same results.
I have pyaudio installed up to date.
Sound recording and playback both work with pyaudio.
The ~/.asoundrc script is here:
pcm.!default { type asym playback.pcm "hw:0,0" capture.pcm "hw:1,1" } # pcm.!default { # type hw # card 0 # } ctl.!default { type hw card 0 } #pcm.record { # type plug; # slave { # pcm "hw 1,1" # } # } Here is the output of the program.
