RealTek HD audio question for AMD780G owners

[merc82]

Not a GBPVR problem but a hardware issue for a common setup in this community.

I have a Gigabyte MA78GM-S2HP motherboard with RealTek ALC889 audio on board. I connect to my AV receiver through optical SPDIF. It works well though there are a couple annoyances.

First to prevent the sound card from resampling all sound to 48 kHz I had to install an ancient driver (ver 1.37) as newer resamples. My concern with using old drivers is that a newer driver may address the second concern.

The second issue, and the one that bothers me most, is the card seems to send a "pulse" to the receiver at system startup (maybe at some application start up?) resulting in a pop from my speakers that makes me nervous for the speakers' health if I ever leave the volume high. My previous setup used coaxial SPDIF and did not have this problem. I'd have thought coax would be more likely to have this issue because there is an electrical connection which there isn't with optical.

Has anyone out there seen this and solved it?

You might try installing AC3 Filter. I'm using coaxial SPDIF and have it set up to not modify the source at all, just send it out to the receiver be it DD, DTS, or regular stereo. Works great.

Thanks for the reply. My audio plays fine with the exception of the speaker pop. I've been a long time user of AC3filter though I dropped it about a year ago to simplify the number of programs I have on the system. I tried the newest version again a few weeks back but it caused video lock up in GBPVR. I didn't bother to trouble-shoot, i just uninstalled.
