Audio stutter, Video is fine

[walter scott]

Using Sage 2.1, Hauppauge PVR 250 cards. Has worked perfectly for nearly 3 years, now maybe twice per hour i will hear a slight "stutter" in the audio, but the video is fine. have tried defragging drives. Computer is dedicated to Sage TV, so nothing else running in the background. I'm stumped!

Now that sounds like a IRQ stutter..Try isolating the IRQs for each card. BTW does it stutter with one card?

Nothing has changed, either hardware or software on the machine, but i will check the IRQs. Am now trying to determine if this occurs on all three cards and both drives, or just one. thanks!

I just experienced this today myself. Try playing around with the audio coders. If video is fine then audio stuttering has to be the codecs because video takes much more bandwidth.

this was my reasoning as well. i tried that with no luck. have just upgraded to sage version 5 and will see if that resolves the issue. meanwhile, plese let me know of any results you have.

When I had this issue, I was testing a new setup and using my tuner machine as an extender to a new non-tuner server. The non-tuner server is hardwired to a gig switch but the extender is reached via wifi. The throughput was worse and I had audio stuttering.

I didnt get my video to stop stuttering but the audio was fixed by installing a more efficient codec from powerdvd. After you install powerdvd you can select it's codecs for audio and video.

I wish this setup worked but it didnt for video so I scrapped it.

thanks! Ive a copoy of power DVD. if upgrading to 5 did not solve the problem, i can try that.

Something occurs to me. If the tuner cards are hardware encoding, and if the audio stuttering is in the file, indicating the stutter occurred during encoding, how will installing and using different software codecs impact this? Does the tuner card somewho reference the software codecs?

Well if that is true then sounds like you got a stuttering card.

Except that i have three cards, and this is happening on all three.
