Does that mean it just doesn't have any > volume control in hardware or it's module's problem? any news on this? I'm planning to buy one, but still don't know if it will work or not. It's a pity that the original poster provided no info either on the results of the test, I mean if he managed to get any sound out of it, stereo or surround. I guess yes since he mentions a softvol he added... What about the volume controls (although I personally don't need any)?

This results in the creation of hwC*D* devices, not the ones listed in the error message. My thanks to Takashi for helping me resolve the problem.

As long as you are copying samples from some buffer into the sound card's buffer, using mmap does not give you any benefit because this is exactly the same as snd_pcm_writei() does.

This is no device file. Something created this file wrongly. Takashi -- Enter the BlackBerry Developer Challenge This is your chance to win up to $100,000 in prizes!
