If there was a way to cap or lock the volume so that _no_ programs (like xmms or mplayer) could turn it higher. That would be great :) I don't know why all programs try to adjust the PCM instead of Master or any of the others. But a cap would be a start ;) ====================================================================== ---------------------------------------------------------------------- rlrevell - 12-31-05 07:26 ---------------------------------------------------------------------- Is this still a problem with the latest ALSA release? I cannot reproduce it (setting volume to 100% with my Audigy2 ZS is loud but not distorted). Make sure bass and treble controls are set to the middle position. ---------------------------------------------------------------------- afran - 01-02-06 19:36 ---------------------------------------------------------------------- Yes, this still seems to be a problem, at least on my card (Creative Labs SB Live! EMU10k1, rev 08). I've tested it with ALSA driver version 1.0.11rc1 (I hope that's the latest release, you have mentioned), and still get distorted noises when PCM is set to more than 74%. I recorded the output of my Creative card with my Terratec Phase 26 (all mixers except Master and PCM left on their default settings) and uploaded the results [1]. You should notice the noise in every file with PCM set to 100% (Master doesn't seem to have any influence on the noise, just makes output louder): - sb.074.074.wav: SB Live! playing at Master 74%, PCM 74%. - sb.074.100.wav: SB Live! playing at Master 74%, PCM 100%. - sb.100.074.wav: SB Live! playing at Master 100%, PCM 74%. - sb.100.100.wav: SB Live! playing at Master 100%, PCM 100%. And just for reference the same original file played with my Phase 26 and recorded with the very same card (that card has only one mixer control, so no volume for Master is given): - phase.086.wav: Phase 26 playing at PCM 86% (default). - phase.100.wav: Phase 26 playing at PCM 100%.

I don't want to leave those files on my server (limited bandwidth) forever, so I probably have to remove them some day without further warning.
