Audio glitch with i3 4170 HDMI

Tue Jun 30, 2015 4:26 pm

I've got a Core i3 4170 powering a home theater PC / server, and it's connected via HDMI to a 40" Philips HDTV. It works nicely for streaming video, and video playback to the TV is flawless with one major exception. Any time an application is playing audio at the time it exits, a flat dissonant tone is emitted that doesn't stop until audio playback is initiated. If you stop the app from playing audio (be it by pausing or stopping it altogether) before exiting, the behavior doesn't happen. What gives? This has inspired me to put a Radeon 7750 into the system because it doesn't give me any guff, but I'd love to know what's making it do that for future reference.

Sounds like a buggy audio driver.

Yeah, it's gotta be. I just don't know how the audio driver can stay crappy across multiple product generations, as I had a similar problem with an i5 3570K a while back. No chance it's the HDMI cable itself, is it? I think that's been the one constant in all of this.

If the audio plays normally aside from this glitch, I don't see how it could possibly be the HDMI cable.

Wouldn't audio over HDMI be an Intel driver if you're using integrated graphics? If so, I'd be less inclined to think it was a driver issue (you'd see huge numbers of people reporting the same problem). It's possible that it's a hardware quirk with your motherboard, or even the device on the receiving end (TV) doing something strange.

I've run multiple HTPCs with i3 2x00 and 3x00 CPUs (and all sorts of different driver revs) and never experienced the issue.

Considering you've had the issue follow you across two different CPUs (and assuming you've had occasion to try different drivers) I agree that it feels like there's something else in play here that's specific to your setup.

Have you tried turning off system sounds? Helped with various audio issues I had with Media Center (though admittedly it was different behavior than you're seeing).

I generally turn system sounds off anyway, so that shouldn't be causing the problem. This isn't down to the HDMI cable either, since I now remember swapping cables to try and isolate the issue a while back. I really think this might just be the TV being somehow uncooperative, but since I've thrown in the Radeon 7750 it's probably an academic discussion anyhow. Thanks to all of you for your help.
