It plays back stereo without problems. I wanted to use the rest of my 5.1 speaker set, so for a test I ran the speaker-test program. Running it without parameters or with 2 or 4.0 channels works also fine. So far so good. But when I run it with 5.0 channels or 5.1 channels the CPU load of speaker-test goes to 100%. I'll show the output of top along with the command lines below (for the 2.0 and 5.1 case) in the "Additional Information" box. ====================================================================== ---------------------------------------------------------------------- bitmage2 - 02-23-06 00:54 ---------------------------------------------------------------------- A similar behaviour is reported here (I also get this behaviour): http://www.mail-archive.com/alsa-user%40lists.sourceforge.net/msg14867.html ---------------------------------------------------------------------- Raymond - 07-11-06 05:58 ---------------------------------------------------------------------- remove .asoundrc , center_lfe is device 3 Issue History Date Modified Username Field Change ====================================================================== 02-23-06 00:48 bitmage2 New Issue 02-23-06 00:48 bitmage2 Distribution => SuSE Linux 10.0 02-23-06 00:48 bitmage2 Kernel Version => Linux 2.6.13-15.8-default #1 Tue Feb 7 11:07:24 UTC 2006 i686 athlon i386 GNU/Linux 02-23-06 00:54 bitmage2 Note Added: 0008164 02-23-06 00:55 bitmage2 Issue Monitored: bitmage2 07-11-06 05:58 Raymond Note Added: 0010964 ====================================================================== ------------------------------------------------------------------------- Using Tomcat but need to do more?
