Onboard Realtek ALC882 Audio - Intermittent Crackle during LiveTV

[Mark1]

Hi everyone,

While watching Live TV in Vista Media Center, I get an Intermittent crackle noise in the audio. The normal audio is still there, its just crackling in the background. Eventualy in goes away (maybe a few minutes or so), or I can make it clear up myself by changing the channel and going back to the original channel.
The crackle will not be there when starting to watch a channel, it just starts randomly at some stage.

I have a Gigabyte GA-8I945GMH-RH motherboard with onboard Realtek ALC882 audio. The latest Realtek drivers have been applied, no change. I have my audio connected to a Sony Amp via Digital Coax cable.

I don't ever have the problem when playing any other audio or video type (.MP3, .avi etc..)
I have no alternative codec install, just using the default MS one. DVD's play fine, even DD and DTS come through fine to the Amp.

Its just Live TV.

It has me stumped.

Any suggestions? Anyone got the same problem? Any Vista audio settings I should look at (eg sampling rate). Does anyone require anymore system information? I just need to be pointed in the right direction.

Mark.

yep me too, although only very minor, i've noticed it is most present when the audio stream switches from mpeg audio to AC3 or visa versa.

A good example is the 7.30 report on ABCTV HD, the channel guide just before 7.30 report is mpeg audio, then the 7.30 report is AC3 audio, always results is lots of audio crackle noise, fortunately within 2 to 3 seconds has completely disappeared.

I'm using the onboard realtek ALC 888 codec, with the realtek vista 32 drivers, audio out is via SDPIF TOSLINK to my Yamaha receiver.

Perhaps we should 'bug' realtek and microsoft about the reproducible issue.

Thanks for the reply.

Always - I won't say good - but comforting to know that in may be a technical issue and not just the way I have things set up when someone else has the same issue.

Anyone else, maybe someone found a fix?

I'll see how this thread goes and then I will contact Realtek and M$ about the bug.

Merry Xmas,

Mark.

Anyone?

I used to get this to. I believe it is actually the video driver that is the issue.

Yeh I know, sounds nuts but when it comes to media centre, anything is possible.

I guess no more takers on this one?



I guess it could also have something to do with the bug in most Dvico tuner cards being discussed here - STRANGE! Channel 9 (not other channels?) WHITE BACKGROUND STUTTER (mostly during ads)
It shouldn't be long before a solution is finally at hand
