Using aplay I can play the provided sample file "sin1000_48khz.wav"
"aplay -Dhw:0,0 sin1000_48khz.wav"
and also other .wav files as long as they are all stereo and 48000bps.
I cannot play .wav files in mono or at other speeds, I have tried various combinations of commands, e.g.
"aplay -f S16_LE -c2 -r48000 test.wav"
But I always seem to get the "unable to install hw params" message.
What am I doing wrong?
