I've tried searching the alsa list archives, but the search always comes up with zero results regardless of term(s) entered.
I have a Dell Latitude C810, which integrates an ESS Maestro3 chip for sound. I am using it's line in jack for recording. What is happening is that the amplitude of samples during recording never exceed appx 26,000. The audio 'clips' at that point, instead of the normal ~32,000 mark. This doesn't seem to affect the quality of the recorded audio. If record levels are adjusted properly, everything below ~26,000 seems good. The only problem with it this way is a slight loss in precision, as the full sample rate amplitude is not being used, and I suppose therefore a slight loss in dynamic range. Also, other programs can't tell when the signal is clipping, because it never reaches the 32,000 mark of normal 16bit audio. I have checked the recording behavior under windows to make sure it wasn't a hardware problem, and everything seems fine under windows, ie full amplitude signal coming in. I have also tried multiple versions of alsa, 0.94, 0.98, 1.01, and 1.02 I think. All versions seem to do the same thing. Is this a known problem, or has anyone else encountered it? ------------------------------------------------------- SF.Net is sponsored by: Speed Start Your Linux Apps Now.
