While arguing about the exact phrasing of the error message might be useful somewhere, I doubt it would be of benefit to the OP, especially since we have no idea if this is actually the problem. I would suggest that the OP send the phone a mono source .wav file. Also why is he using the hw: ? That ensures that if there is any discrepancy nothing can happen. That tells alsa to not try to make the signal conform to the card in any way, but to send it straight out if it can, and to fail if it cannot. Why not let alsa at least try to make the signal conform to the card by removing that hw: requirement? ------------------------------------------------------------------------- Take Surveys.
