Hello, >Does anybody have full duplex audio working on the DVEVM? It is impossible because drivers have logic bug... I found that it is stop on wait_for_completion_interruptible(&s->wfc) because completion s->wfc never complited in some cases. But I cannot determine yet why it is happens. Among other things I have found that if enable a debug logging in function audio_stop_dma that a problem disappears. May be problem is happens when sound_dma_irq_handler resume audio_read by calling complete(&s->wfc) and right after that it call audio_stop_dma. In this case audio_stop_dma work simultaneously with audio_read (that do setup dma transfer) and it can be problem. But i am not sure and i need time to check it.
