Hello

I finally got my 5.1 sounds working with VLC player, thanks to "Win32 Waveout extension output" tip. I have one guestion in which I did not find answer with quick search. Now that I got my 5.1 sounds working through A/52 over S/PDIF, I cannot no longer change the volume with VLC Player.

Is there any way for me to change volume level with VLC or am I stuck in changing volume from my amp?

Iam using Asus A8N-E integrated audio and 3.94 drivers from Realtek. I have tryed to change volume levels from windows but the S/PDIF volume is greyed out and I cannot adjust it.

A S/PDIF port is a pass through. No control of volume is available.

Agh another problem. After doing the S/PDIF tweak "Win32 waveout extension output" to get 5.1 sounds working I realized that sound control was not what it used to be.

Total volume level had dropped atleast to half with non AC3 files and boosting over 100% sound level with VLC did nothing. Tried to uninstall (delete preferences) and install VLC player again but no help. After awhile I had to restore a couple days old ghost backup and everything was fine again.

Very weird stuff and at the moment Iam sticking away from that S/PDIF tweak and 5.1 sounds, not worth the trouble of losing sound. Any ideas what could cause this? I did not install or do anything out of the ordinary during the couple days I tested 5.1 sounds through S/PDIF, just realized today that all the other sounds were dumbed down :(

You will need to investigate further as what you are describing for volume control is normal with or without S/PDIF

In other words 50% volume is the default or unity gain (full up) of most other players. From 50% to 100% is 6db of gain. Going past 100% there is no change in Windows. Try changing the system volume as 6db of gain often causes distortion in the front end of sound cards.
