The Human voice (center) come out from rear speakers aftewards. 1) speaker-test -c 4 -D hw:0,0 2) using xine to play 5.1 channel-test audio samples with FFTScope enabled. the above tests indicate that the front and rear channels are swapped after the first play. Please let me know if you also have this problem on your MX300. The hardware equalizer of au8830 sound much better than the software equalizer of XMMS. There are follow up about how to fix 32/64bits issues related to the equalizer and features not presented in au8820. http://sourceforge.net/mailarchive/message.php?msg_id=11997399 alien seem have no interest to test the hardware equalizer because of the hang oops.
