I have done both the 7399 driver and the 7432 and when I plug in my headphones, the EQ disables. That is my main use, so I would love to know if there is a way to adjust an EQ with headphones and the Surface Pro 3... Any help?
I only ever use MusicBee as the music client, and listen to music via headphones that are plugged froS3 into external speakers, or through an FM transmitter in my vehicle (S3 plugged in to transmitter which is then tuned in to my vehicle stereo).
Sorry for reviving this thread, but it's still up to date. I tried to do it as OP described for the Surface Laptop which has Dolby as well, with the Driver Version 8237, but at the point where I install DolbyDigitalPlusAA.exe, its gives an error saying "Dolby Digital Plus needs to be installed". Any ideas?
