I'm quite sure that all output connections (from either the inputs or the playback channels) are made through the HDSP mixer. However, it's quite possible that the HDSP FPGA sets up default unity-gain connections between the playback channels and their corresponding outputs (and mutes all of the connections between hardware inputs and outputs) when it's initialised. This would explain why snd_hdsp works (i.e. you can playback and record through the default I/O), although amixer doesn't do anything: the driver doesn't have to set up any default connections, because those are part of the FPGA reset state. I would be surprised if snd_hdsp could set up connections, but amixer couldn't. I provided that sample script which tells amixer to disconnect everything so that you could see if _any_ amixer matrix mixer controls have an effect on your card (because if they did, it's possible that the 9652 simply has a different matrix mapping). -- Roger Williams <[EMAIL PROTECTED]> Qux Tool & Die, Middleborough, Massachusetts // Omne tulit punctum qui misquit utile dulci // ------------------------------------------------------- This SF.NET email is sponsored by: FREE SSL Guide from Thawte are you planning your Web Server Security?
