- Noise when watching TV
- Posted by Bill Marriott on February 13th, 2006
Hi,
I finally ditched my ATI All-in-Wonder. Well, actually I ditched the whole
rig. Here's what I'm running now:
DFI LanParty UT nF4 SLI-DR Expert Rev A
AMD Athlon 64 X2 4400+ Toledo
2x1024MB Corsair XMS DDR500 (TWINX2048-4000PT)
2x Maxtor DiamondMax 10 6L250S0 7200RPM SATA 150 HDD
LITE-ON SHM-165H65 DVD w/ LiteScribe & DVD-RAM Support
eVGA 256-P2-N527-AX GeForce 7800GTX
Hauppauge WinTV-PVR 500 MCE
ENERMAX Liberty ELT620AWT ATX12V 620W Power Supply
Windows XP Media Center 2005
I've set up the system successfully. I'm using the latest drivers downloaded
this weekend from the Hauppauge site, and I've purchased the nVidia
PureVideo Decoder (Gold) as my decoder.
The problem is that unpredictably, when I change channels, the sound will
switch to a kind of digitally distorted squeal, noise, static, distortion,
whine....
Whatever you want to call it, it sounds bad. Changing the channel a few
times will clear it up (could be just one channel change, could require
multiple ones). Sometimes quitting and relaunching MCE will clear it up
(until the next channel change). And sometimes that won't fix it either.
When the audio is correct it sounds fabulous. Sometimes I can change
channels several times without encountering the squeal. Other times it
occurs the very first time I attempt it.
The whine is present (or not present) in the digital recordings (or playback
buffer) as well. In other words, if I specify to record a show, it may have
the whine actually stored in the .dvr-ms file. When the distortion is
present, it never goes away on its own. A channel change or re-launch of MCE
is always required.
This noise problem was present from the very beginning and has persisted
through a couple reinstalls of WXPMCE.
Ideas? Suggestions?
Bill

Have you tried it with another cable and/or connector already?

Actually a poor connector/cable would present consistent noise across all
channels, or at least on the same channel. (i.e., channel 43 would always be
noisy.)
As it is I can switch back and forth between 44 and 43 and 43 will
eventually clear up.
Actually, I discovered the problem. This is a dual tuner card. One of the
tuners seems to be defective. I tested this by:
1) Changing channels until I received the "noise"
2) Pressing Record
3) Tuning to another channel.
Once I occupied the one tuner with the recording, I could switch among all
the various channels to my heart's content and there was no noise, just
perfect signal. I verified my theory by:
4) Pressing Record on one of the good channels
5) Returning to the noisy channel and stopping the recording
6) Changing channels
When I did this, all channels had noise and I could not coax out a
clear-audio channel.
Apparently, MCE was dynamically selecting one or the other tuner as I was
changing channels according to which was "ready" or not. This gave the
appearance of a random glitch. Kind of tricky to spot, I guess 
Now, follow-up *BONUS* question for the group: until my replacement card
arrives, how would one disable the bad tuner temporarily, making MC think I
have only one tuner, so that I can be sure any recordings I have over the
next couple of days are crystal-clear?

Cool! Nicely done.
You can disable a tuner in your Device Manager;
Rightclick on My Compter-> Manange-> Device Manager
