Hi list, I gave PulseAudio a try and it seems to be working fine so far There is a small problem with volume controls. When I reduce the PA volume control below 16%, then volume is muted entirely. Apparently this happens because the ALSA "Master" control reaches 0%, which mutes all sound output on my hardware (even though the ALSA "mute" flag is not set). This seems hardware-specific, as I haven't seen this behavior on any other computers; usually 0% volume still outputs some level of sound. I tried with kernels 2.6.32 and 2.6.33, PA 0.9.21, ALSA 1.0.21. The sound chip according to ALSA is SigmaTel STAC9205 using the HDA driver according to lspci: 00:1b.0 Audio device [0403]: Intel Corporation 82801H (ICH8 Family) HD Audio Controller [8086:284b] (rev 02) I tried working around this by changing the PCM level in alsamixer, but whenever a new client connects, PulseAudio thinks it's smarter than me and resets the PCM mixer -- to somewhere between 0.00 ... -0.60 dB (?!), and sets the master level to 0% again So there are 2 distinct problems: 1. The STAC9205 ?0% volume quirk needs to be handled somewhere 2. If PulseAudio wants to maximize some volume controls, it should set them at 0.0 dB, not -0.60 dB Regards, Marti Raudsepp
