Hi, I have a internal intel hda soundcard and a external aureon 5.1 usb mk2 sound card. they are both supported by alsa and the aureon card even has excellent alsa support according to the alsa wiki (http://alsa.opensrc.org/index.php/Terratec_Aureon_5.1_USB_MK.2 ). The aureon card doesn't have a hardware mixer, so pulsaudio (alsa?) has to upmix stereo sounds to 5.1 which works quite well, but: i can't hear any bass until i switch to my internal soundcard for playback and back the aureon card. when i pause my music/sound even for just a second, the bass is gone again. also, adjusting the volume sliders for the different channels in pavucontrol either changes nothing or multiple channels at once (for example, the low frequency channel has no effect). what i already tried (thanks to coling from #pulseaudio): - disabling module-suspend-idle - module-udev-detect with and without tsched=0 - uninstalling openal some debugging stuff: pacmd ls output (with bass working): http://pastebin.com/k388d5ZD pacmd ls output (with bass not working): http://pastebin.com/xdW1Ra1K pulseaudio -vvvvv output (i started pulseaudio in debug mode, then i started playing a song with mpd (bass not working), then i switched to my internal intel soundcard for a second and back again (bass working), then i paused playback in mpd for a second and started playback again (bass not working again) : http://pastebin.com/0xkyreXe Thanks in advance!
