Hello, I'm running Mandriva 2009.0 RC1 with PA 0.9.12 (from the tarball) that I compiled myself. Right now my worst problem with 0.9.12 is severe (loud!) crackling whenever multiple streams are active at once. I am using alsa kernel and lib 1.0.18rc3; previously I tried ALSA 1.0.17 with the same exact results. You might also be pleased to know that I am stubbornly using one of those pesky and oft-broken snd-hda-intel cards! :) Here's a simple way to reproduce the issue: $ for (( i = 0; i < 2; i++ )); do #Pick a wav file that exists on your system paplay /usr/share/sounds/shutdown.wav & done In 0.9.10 and prior, this would play the same sound file twice on top of itself in very rapid succession, which would make it sound pretty loud, but there wouldn't be horrible crackling. With 0.9.12, it sounds like the loudness of each sound is combined, creating an amplification that is _way_ overdriven, and hence the distortion. This occurs much more noticeably in wav files that are normalized to 0dB, meaning that the loudest parts of the file are set at 0dB. For very quiet sounds whose internal structure consistently maintains a relatively low volume, this effect is almost invisible. Being normalized to 0dB has never been a condition causing this to occur before; previous versions of pulse could play the same wave files just fine without overdriving. Have the maths for resampling/mixing changed now? And is this intended or accidental? My config files are pasted: http://rafb.net/p/jW16b668.html and http://rafb.net/p/cUUFj679.html Thanks, Sean
