Hi guys,
Don't know if this helps you but I was experiencing low sound volumes when playing dvds but all other sound levels were fine (ie windows beeps and system sounds etc.).
Installed AC3 audio filter and went into the control panel for that and incresed the master gain. now my dvds play at an acceptable level.
Start Menu -> Programs -> AC3Filter and run AC3Filter Confiig. Increase the Master at Gain, click Apply and OK. You will notice that the DVD movie volume has been increased.
Sorry I don't know enough about sound to see why this works but it worked for me.
Hope this helps
Now if only can sort out low mic volume issue
Regards
Rob
