I've had this software for a couple of days now, and am having some issues that I just can't seem to sort out. System specs are as follows (let me know if you need more)...
-PowerDVD v 19.0.2403.62
-Windows 7 32bit SP1
-4GB ram
-Intel i7 CPU
-Realtek High Definition Audio driver v 6.0.1.6077
-Gigabyte X58A-UD3R main board
The Realtek audio interface is obviously integrated, and I'm also running an EMU sound card from a PCI slot. Realtek is selected as default for both input and output. And in case it matters, I bought this purely for listening to DVD and Blu Ray music in 5.1 surround sound. I've done my best to turn off all video related enhancements in the software.
Prior to buying this software I was using VLC for DVD surround sound playback, but needed something that would handle Blu Ray as well. Using VLC I trimmed out each speaker with my SPL meter and the Realtek Audio Manager. Things sounded pretty balanced. After installing PowerDVD I'm noticing a number of issues and quirks. Some of which probably stem from me not understanding how the software is handling the audio at any given time. Most notably, speaker balance is way off compared to the settings I used with VLC. The center speaker is strong, while the fronts were almost inaudible and I was getting nothing from the side speakers (even with the trim values set to +10). Only when I changed PowerDVD audio to "8 Speakers" and set Realtek to 7.1 did I get signal form the side speakers. And like the fronts it was extremely weak compared to the center (still with trim values cranked). There's also a lot of noise going on. Some of it seems to be actual distortion (which has prompted me to keep the main volume down to 1 or 2 while tinkering), but there's also a good bit going on within the noise floor as well. It's as if something early in the signal chain is super hot, but is being tamed down (to almost nothing in all but the center speaker) later on.
A few things I've noticed that aren't making sense to me... When playing a DVD I can adjust any of the settings in the Realtek Manager, but with Blu Ray discs nothing (other than the main volume) has any effect. At times while I'm tinkering with either a DVD or Blu Ray playing, the audio has stopped all together and will not resume regardless of what settings I change. It makes me wonder if that distortion I'm hearing isn't a sign of something getting too hot, and eventually shutting down? If I shut down and give it a break for a bit it always comes back. But that alone bothers me a great deal. Clearly I don't know what's going on, but it seems as if this software is trying to muscle its way around my computer without giving me any way to control it.
A bit about my audio settings (again - let me know if you need more)...
PowerDVD:
-Speaker Environment = System Default (8 Speaker) <-- again... only way I can get 5.1 audio to work?)
-Output Mode = "No Effect"
-Dynamic range compression is set to "full"
-Output sync is set to "0 seconds"
-"Exclusive audio output" is not turned on. What exactly is this setting anyway? It's very vague. Does it only aply if you're using a WASAPI output? Which "device" is it talking about sending audio "exclusively" to? My Realtek manager settings still don't bevave the way I expect them to (if at all) regardless of weather or not this box is ticked.
Realtek Audio Manager:
-Speaker Config = 7.1 with Center, Side, and Rear speakers turned on and Sub turned off (my fronts and subs are managed by an outboard crossover)
-Front speakers are set to full range while surrounds are not.
-Bass management is turned off
-No sound effects or equalizers are turned on or in use
-Room correction has all "distance" compensation set to zero, and all trim settings are set to +10 aside from the center speaker and sub which are at +0.
-Audio format is at 24 Bit Depth, and 48kHz Sample Rate. I am able to adjust this to anything between 44.1 and 192 sample rate at either 16 or 24 bits.
Sorry to have been so long-winded here. Just trying to get as much info in as I can. I think what I could really use is a tech-minded person that can explain to me what's happening with the audio from source (disc) to speaker output. I've used countless pieces of audio software over the years. I'm not saying that I've never had issues - but I've never come accross something as "full-fledged" as PowerDVD that seems to have so little in the way of control options in the settings interface. Either I'm missing some deep settings somewhere, or PowerDVD is just supposed to know how my audio should be managed and my computer settings are not in line with what it expects.
Again... Sorry for the long post. Any thoughts would be very much appreciated.
Regards!
