description |
When playing sound in Jaunty out of my HDA Intel SPDIF out, loud sounds clip. This is audible because from the strong distortion it produces, which I have seen some people characterize as "crackling". For example, if I go to system->preferences->sound and play the test sound, the sinusoid is audibly clipping. I have all of my sliders in alsamixer zeroed except for master (@100) and IEC958 (@100). Note that if I turn down the volume of the master and/or the IEC958, the clipping is still present---I've gone as low as -21dB (64/100) on both sliders simultaneously, and the clipping is still there.
I looked around for solutions, this sounds similar to my problem:
https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/285866
However, as I noted, I've tried reducing my levels, and my PCM mixer level is all the way at 0 (-58.50 dB) anyway. Not to mention that these are digital outputs, so having them at the 0dB gain position (100% for the master and IEC958 sliders) should be fine...
Yes I am certain it's not my speakers clipping.
Oddly enough, at one point I was able to get it not to clip in the gnome sound settings control by going through some sequence of trying different backends (various options for ALSA, for OSS, etc.). I have not been able to reliably reproduce the non-clipping, but I will keep trying.
For some reason, I hear the clipping when I listen to music using gnome-listen, but not when using Amarok using Xine as the backend.
Please help me stop the clipping.
