[alsa-devel] unable to do simultaneous playback and recording

[prashant chopade]

Hello,


How to check my AT91SAM9263-EK - AC97C hardware driver is not supporting simultaneous playback and recording of an audio?

Thanks & Regards,
Prashant C.

ALSA _does_ support full duplex, if the hardware and driver support it.
