[QUOTE="joecrow, post: 1193504, member: 128337"] Further to the last 2 posts I also ran the update, all was good on my desktop PC but I had a problem with it on my HTPC. Initially everything looked OK but following a resume from sleep I had an audio problem, there was a slow beating noise coming from the speakers (lower than 50hz hum) and no other audio worked. Power cycling the HDMI connected AVR, closing MP1 and TV Service, signing out all failed to clear the problem, In the MS audio "playback devices" setup any attempt to change or test the setup resulted in an error message indicating something else was already playing on the AMD HDMI device and only a reboot cleared the problem. I was using the latest AMD Catalyst drivers (15.7.1) available for my graphics card (now considered a legacy product so nothing newer) but I did try a Beta test version of the Crimson drivers for my card, which worked.:) However I do not like the limited settings available with the Crimson driver package so went back to Catalyst, confirmed the problem again then simply used the Crimson package to just upgrade the audio driver, which also resolved the problem. In conclusion it does appear that MS have done something to sleep/resume that does effect older AMD HDMI Audio drivers.(n) [/QUOTE]
