script to gather ALSA config info
Can you please run this script on the affected hardware to gather ALSA config info? It would be very helpful to run this on x86_64 and i386 so we can compare the config differences. Thanks.

alsa-info on x86_64
We have run the script on test machine. Here is the output on 64bit system.

alsa-info on i386
alsa-info output on 32bit system.
Updating PM score. Looks like this might just be a configuration issue. Can you look at all the settings in alsamixer for i386 and see if the settings are the same as alsamixer settings for x86_64? You may try saving the saving settings to file on x86_64 (file is called asound.state): "alsactl store" Then install the asound.state file on the i386 system and restore settings: "alsactl restore" we can hear sound from the front right/left channels, while no sound can be heard from the channels of rear panel. Brian, Here are the steps we did for Comment #5. Still no sound from the rear panel. 1: Run "alsactl store" on RHEL5.3_x64. 2: Enter RHEL5.3_x86. 3: Copy file:"/etc/asound.state" from RHEL5.3_x64 to RHEL5.3_x86's "/etc". 4: Run "alsactl restore". And then test Multi-channel on RHEL5.3_x86. The testing result is also same with the previous result: Only the front right channel and front left channel have sound. No sound can be heard from the other channels of rear panel. hello, Brian Copy asound.state does not help on my McCreary platform. Recently we tried latest 2.6.30 rc2 kernel, and found out we can hear all channels sounds output then. It's strange x86_64 platform audio output is okay but x86 not work. Any hint about the difference? thanks! Lisa, Can you give me test results for this with latest RHEL 5.4? Wondering if we need to move this to RHEL 5.5. I tried with RHEL 5.4 SP5 with 2.6.18-160.el5 kernel, I can get audio output from rear panel's front left/right. [root@osve-mc initial]# uname -a Linux osve-mc 2.6.18-160.el5 #1 SMP Mon Jul 27 17:28:29 EDT 2009 i686 i686 i386 GNU/Linux for 5.1/7.1 channel, we will give updates at next monday. 5.1 channel: on both x86/x86_64 2.6.18-160 kernel, we can get audio output from rear panel's back panel jacks. Closing this as current testing shows this is working in RHEL 5.4. |
