Low Volume in GBPVR, Normal Volume In GraphEdit

[dennit]

Problem: Volume is very low when playing a file in GBPVR. When playing the same file in GraphEdit (render media file) or in Media Player Classic Home Cinema it is very loud.

System: I send audio via SPDIF coax to my amp. The SPDIF coax connects to the motherboard, and it uses Realtek HD Audio Manager set to 5.1 audio

PVRX2: I have tried setting audio renderer, audio decoder and AC3 decoder in config to system default.
Here is what the log says about filters used when set this way:

Code:

2009-07-18 08:39:55.314    VERBOSE    Graph contains the following filters:
2009-07-18 08:39:55.314    VERBOSE     - Default DirectSound Device
2009-07-18 08:39:55.314    VERBOSE     - Video Renderer

This has low volume.

GraphStudio renders the file and plays it loud using 4 filters:
- AC3Filter
- Default DirectSound Device
- CyberLink Video/SP Decoder (PDVD7)
- Video Renderer

This looks the same to me, but if it is, why is the volume so much lower?
My normal setup for GBPVR uses these filters:

Code:

2009-07-18 08:31:37.480    VERBOSE    getSetting(ListGraphFilters)
2009-07-18 08:31:37.480    VERBOSE    Graph contains the following filters:

2009-07-18 08:31:37.480    VERBOSE     - CyberLink Video/SP Decoder (PDVD7)

2009-07-18 08:31:37.480    VERBOSE    getSetting(SaveGraphFiles)

This also has low volume.

My volume setting is Master volume, but I've also tried "none-internal."

Does anyone have any comments about why GBPVR is playing at the lower volume than other programs? 99% of programs are playable by turning the volume up, but then I get blasted when I leave GBPVR.

Thanks.

As usual, I figure it out after I've given up and asked. The answer is that under Vista I had to click the volume icon in the tray and choose Open Volume Mixer. There is a separate volume slider for PVRX2 and for Windows Applications, as well as for the digital output. The Apps setting was high and PVRX2 was set to minimum.

I haven't seen this separate volume control in the mixer for an application before. I'm not sure why PVRX2 was set low, while the other programs were set high. Anyone who wants to help me understand this better, please feel free to post.
