Ladies & Gentlemen:

After upgrading from ALSA .14 to .17 on my CentOS 5.2 machine, my HR950 no longer yields audio. Below is what a dump of dmesg reveals.
How can this be resolved? It appears to be a kernel module versioning problem. However, when I do a modprobe -f em28xx_alsa to force the module to load, and attempt to run mplayer (mplayer tv://59 -tv driver=v4l2:device=/dev/video0:chanlist=us-cable:alsa:adevice=hw.1,0:amode=1:audiorate=32000:forceaudio:volume=100:immediatemode=0:norm=NTSC) I see the information even further below on the terminal. I built and installed ALSA driver, lib and util .17, installed them and rebooted. I have seen this problem posted many times on different sites on the web and there were no resolutions. What is up with this? I even rebuilt v4l2 after installing ALSA .17 and I still see this.

All:

I have searched on the web and it seems that at least one person has overcome the problem I am having by rebuilding soundcore.ko (See here:
http://redmonk.com/sogrady/2008/04/29/sog-1-busted-sound-0-getting-audio-working-on-the-x300-under-ubuntu/).
There is a sound_core.c in the ALSA tar ball. Why doesn't ALSA rebuild the soundcore.ko module? The functions that em28xx_alsa is complaining about reside in soundcore.ko according to my research. Basically, I downloaded .18rc3 driver, lib and util and configured, built and installed. I rebooted and em28xx_alsa complained that symbols that resided down in soundcore.ko did not jive with the versions of the same symbols for which it was trying to resolve linkages. I rebuilt the video4linux code, reinstalled and rebooted and the problem was still present. It looks as though one should be able to build an new soundcore.ko with a ALSA package but there are no instructions on how to do so. Please help!!!

Best Regards,
