SPDIF Volume Control? (1 Viewer)

[sleepycol]

Hi,

I have a HTPC using optical SPDIF out into a dolby digital amp. Therefore I just allow all pc sounds to be passed through to the amp for decoding. Amp is 7.1 surround but I just have 5.1 speakers currently.

At the moment when I alter the volume in MP it just controls the left and right speaker. The other speakers continue playing movie sounds or music (up-mixed to 5.1 in MP config). It would be great if the volume adjustment controlled all speaker volumes.

Is this possible?

Cheers,
Colin

For me it volume control works when MP is not in full screen, but in full screen the volume is fixed...

If you use volumetracker (for XP only, as Vista has this function in built) it links master volume and wave volume together, if changing one or the other results in changing volume of all 5 speakers then this would solve your problem.

Hi,

I have tried setting volume controls in MP config to adjust master and wave volume but this doesn't help control all 5 speakers. Wouldn't volumetracker do the same thing as MP config and therefore not work?

I just tried VolumeTracker, and it works great. Again a small improvement on my systems. Getting better all the time

Run MP in windowed mode
Adjust the volume by loading the volume mixer in the task bar
Check to see if (1) master or (2) wav volume has any effect on all five speakers
If it does then volume tracker may solve your problem

Hi,

Changing the master volume slider in taskbar volume properties has no effect on any speaker volume. Changing wave volume slider only effects the front left and front right speakers. Centre, sub, rear left and rear right speakers remain at full volume. I guess this means that volume tracker would not help?

Maybe MP devs could allow an option in the volume config to control the spdif volume? (at present you can chose wave or master so it would be nice if spdif could be selected there). If indeed it is possible to control volume of spdif outputs?

Cheers,
Colin

The nature of SPDIF means there is no volume control bc the sound is past directly to the receiver for decoding. The only way of adjust SPDIF volume is to decode the audio stream, apply gain, then re-encode and pass to receiver.

I use AC3 filter, but I guess that wouldnt help as when I adjust volume it will not adjust anything within AC3filter.

My volume controls (standard systray volume window) do have a slider for spdif but irs greyed out so cannot be adjusted. I wonder if there is a way of enabling this adjustment?

I don't understand why you guys want this feature? The WHOLE point is that your adjust the volume on your AV amp/receiver, the same place where your audio should be decoded...
