[kwlug-disc] Audio device not detected?

[Khalid Baheyeldin]

I found a workaround for the "Channels count non available" error.

Basically, it has to do with a .wav file generated by pico2wave being
mono, while the sound card is stereo.

So I use sox to do that part, as follows ...

# Generate the .wav file from the text
cat /tmp/input.txt |
   /usr/bin/pico2wave -l 'en-US' -w foo.wav

# Convert the mono .wav file to stereo
/usr/bin/sox foo.wav stereo-foo.wav remix 1 0

# The stereo .wav file is played through the speaker
/usr/bin/aplay -q -D hw:1 stereo-foo.wav
