Dropped and glitched sound with dv9700 when watching Blu-Ray over HDMI connected to receiver

‎01-03-2009 04:58 PM

I have hooked my dv9730nr up to my receiver (Onkyo TX-SR606) via HDMI, which then passes video through HDMI to my Panasonic plasma.  When I do this, Blu-Rays have an audio glitch every 4-6 seconds, which sounds like either quick repeated sounds or a half-second pause in audio.  The audio and video otherwise are great.  PowerDVD Ultra reports that I am outputting 5.1 Dolby Digital via PCM, and the sound from my speakers support this.  With other video, including 1080p .WMVs that I've made myself, there is no problem.  I've disabled the laptop's monitor, and am only using the TV as my display.  When I bypass the receiver, and hook my laptop straight into my TV via HDMI, there is no problem, but my TV has no built-in speakers, so no audio is being passed via HDMI.  I have no other receivers with HDMI to test my laptop, so I'm not sure that that the problem is not with the receiver.  I've tried disabling all audio output modes except for 24bit 48KHz under Realtek Digital Output in the Playback Devices control panel.

 

I'm not worried about this, since I have a dedicated Sony Blu-Ray played on the way, but I am disappointed in the HDMI audio performance of this laptop.  I suspect the problem lies in the Realtek HD Audio drivers, or something wrong with the related hardware on the motherboard.  I updated my drivers from v6.0.1.5494 A to v6.0.1.5548 A, with no change.  I will try driver Vista_R213 off the Realtek website, although I'm not sure that this is compatible with my laptop.

 

Any ideas/suggestions?

 

Specs:

Windows Vista Home Premium 32bit SP1

Intel Core 2 Duo T5450 @ 1.66 Ghz

3 GB RAM

nVidia GeForce 8600M GS

RealTek High Definition Audio

Well slap me twice and call me Sally, it would appear these new Realtek drivers fixed the problem.  The drivers can be found here, but be prepared for a slow connection to the Realtek website.  Now I can indeed enjoy video and sound the way it's meant to be done via Blu-Ray, kudos Realtek for fixing this problem.
