I can render stereo sound to a WAV file, it just does not work for real‑time playback.
I get these two errors:
Expression 'parameters->channelCount <= maxChans' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 1438
warning: could not open audio, error -9998, Invalid number of channels.
I searched the documentation about global variables named channelCount or maxChans with the hope to set, say a *channelcount* to 2, but found nothing like this.
Surprisingly, I came back to the LSP file, wanted to play it again, and it worked, and I changed nothing.
It did it multiple times again: it sometime works, sometime not, randomly. The most of the time it works though.
