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 01:45 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. ====================================================================== ---------------------------------------------------------------------- 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. :-| ---------------------------------------------------------------------- rlrevell - 07-15-06 01:45 ---------------------------------------------------------------------- Well, you could just install over your current drivers, then if it does not work, reinstall the version that your distro supplies. "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. :-|" Sorry, that's just how Linux works. There is very limited manpower to support an insane amount of hardware and we don't have the resources to go back and fix 50 old versions every time a bug is found. If you want support for the latest and greatest hardware you need to run a recent version. A year is a LONG time in the Linux world.
