I have a USB sound card that only accepts unsigned 8 bits format (a tux droid).
That works fine with plug but I can't get dmix working as SND_PCM_FORMAT_U8 is
not in the supported formats of dmix.
static unsigned long long dmix_supported_format =
(1ULL << SND_PCM_FORMAT_S16_LE) | (1ULL << SND_PCM_FORMAT_S32_LE) |
(1ULL << SND_PCM_FORMAT_S16_BE) | (1ULL << SND_PCM_FORMAT_S32_BE) |
(1ULL << SND_PCM_FORMAT_S24_3LE);
Is it possible to do the mix in another format (S16_LE) then have plug do the
resampling to 8bits? Otherwise could I do that with Jack? Or can I imagine
patching dmix to add support for 8 bits (maybe dreaming here ;-) )
Thanks for your help,
David
