A NOTE has been added to this issue. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1869> ====================================================================== Reported By: bitmage2 Assigned To: ====================================================================== Project: ALSA - driver Issue ID: 1869 Category: CORE - pcm Reproducibility: always Severity: minor Priority: normal Status: new Distribution: SuSE Linux 10.0 Kernel Version: Linux 2.6.13-15.8-default #1 Tue Feb 7 11:07:24 UTC 2006 i686 athlon i386 GNU/Linux ====================================================================== Date Submitted: 02-23-2006 00:48 CET Last Modified: 07-15-2006 01:28 CEST ====================================================================== Summary: Playing surround sound produces 100% CPU load Description: I am using the CS46xx with a Hercules Gametheater XP 5.1 . 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. ====================================================================== ---------------------------------------------------------------------- rlrevell - 07-14-06 22:57 ---------------------------------------------------------------------- By "too old to debug" I mean that even if the bug is found, a year old ALSA version can't be fixed - the answer will be to just upgrade. 1.0.12-rc1 will work with 2.6.13. We need to determine whether the bug is present in the latest version, so you'll have to try 1.0.12-rc1. ---------------------------------------------------------------------- bitmage2 - 07-15-06 01:28 ---------------------------------------------------------------------- Info: I can confirm that the bug is there in ALSA 1.0.10rc3 , Linux kernel 2.6.15-23-386 (just downloaded Kubuntu 6.06 just for checking this). My check against "1.0.12-rc1" will take plenty of time, because it means to find a spare HD/filesystem, install a Linux distribution, get ALSA compiling (it is more than a year since my last compile/install of ALSA). If I find a current live CD, it might speed up the process. Chris PS: I am still somewhat astonished, that a driver/library/whatsoever being younger than a year cannot be fixed. Actually, if installing drivers wouldn't be so complicated and time-wating on Linux, I wouldn't care so much. :-| 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 07-14-06 20:57 bitmage2 Note Added: 0011004 07-14-06 20:59 bitmage2 Note Added: 0011005 07-14-06 21:25 rlrevell Note Added: 0011006 07-14-06 22:40 bitmage2 Note Added: 0011008 07-14-06 22:57 rlrevell Note Added: 0011009 07-15-06 01:28 bitmage2 Note Added: 0011013 ====================================================================== ------------------------------------------------------------------------- Using Tomcat but need to do more?
