HVR1600 and Centos 6.2 x86_64 -- Strange Behavior

Dear LinuxTv and AtRpms Communities:
     In the most recent three kernels {2.6.32-220.7.1 ;
2.6.32-220.13.1 ; 2.6.32-220.17.1} released for CentOS 6.2 I have
experienced what can only be described as a strange behavior of the
V4L kernel modules with the Hauppage HVR 1600 Card.  If I reboot the
PC in question {HP Pavillion Elite M9040n} I will lose sound on the
Analog TV Tuner.  If I Power off the PC, leave it off for 30-60
seconds and start it back up then I have sound with the Analog TV
Tuner every time.  Not sure what is causing this, but thought the
condition was worth sharing.

Could you please clarify which HVR-1600 board you have (e.g. the PCI
ID)?  I suspect we're probably not resetting the audio processor
properly, but I would need to know exactly which board you have in
order to check that.

Also, if you not done so already, verify that it is not a sound card playback issue.   Make a recording when you suspect the HVR1600 is not capturing sound. Then play the recording when you know your sound is working.

Also, does audio line in with Svideo or CVBS exhibit the same symptoms?

I had to go through a good bit of trial and error to get the CX23418's APU to capture audio reliably after boot up, so I am reluctant to mess with that unless needed.

We will want to try to narrow the problem down to one of the analog tuner, integrated CX25843, or APU.

Regards,
Andy

First Question the PCI ID -- the output of lspci -v is :
01:00.0 Multimedia video controller: Conexant Systems, Inc. CX23418
Single-Chip MPEG-2 Encoder with Integrated Analog Video/Broadcast
Audio Decoder
        Subsystem: Hauppauge computer works Inc. WinTV HVR-1600
        Flags: bus master, medium devsel, latency 64, IRQ 17
        Memory at f4000000 (32-bit, non-prefetchable) [size=64M]
        Capabilities: [44] Vital Product Data
        Capabilities: [4c] Power Management version 2
        Kernel driver in use: cx18
        Kernel modules: cx18

And although right now I cannot find the earlier instructions I
followed there was a post on the gossamer threads about the audio not
being detected and the card muting the output.  There was a command
{memory fails me right now} to query the card for the status of the
tuner which is showing the audio is undetermined and muted when this
issue happens.  It happens in both mythtv and cat > file.avi
recordings played back later.  It should be noted that audio playback
is fine despite the analog video sound being muted.

Bob Lightfoot

P.S. -- David & Andy - If you need more specific information just send
me the commands to run and I'll provide the feedback,

P.P.S. -- Appreciate all you guys do -- my linux video box runs
circles around my Vista Media Center.

Last P.S. - Linux Media Rocks.
