I've been struggling with this problem every since I bought my new Lenovo P620 in September. My Realtek rear audio port goes into some sort of suspend mode after 10 seconds of idle time and is taking almost 1 second to wake up causing all audio to miss the first second of sound. This ALC 4050H Codec can be found in most AMD motherboards and USB headphone dongles requiring no audio driver. It seems the Lenovo P620 is the only computer having issues with the Realtek driver as a web search found no such issue except for the P620. The P620 has quite a few audio issues with Ubuntu Linux requiring several patches to be designed. If I use the Windows USB Audio 2.0 driver, the problem goes away. Unfortunately, the Realtek software no longer recognizes the device and the auto switching of ports no longer works... if you plug headphones in the front jack, the rear audio speakers continue to play.
I've tried several drivers from other AMD motherboards using the ALC4050H Codec and most won't install correctly as they have drivers for other Realtek devices like ALC1220. The ASUS Realtek driver is interesting as it has a small .reg file signed by Shawn Brink from TenForums.
I've contacted everyone... Lenovo, Realtek and a bunch of other forums. My knowledge of computers is above average and I've tried the normal registry tricks like changing the power scheme in "[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e96c-e325-11ce-bfc1-08002be10318}\0002\PowerSettings\] "IdlePowerState"=hex:02,00,00,00... changing the value to hex:00,00,00,00 has no effect as the driver is following it's own "IdlePowerState"
Perhaps someone might have a suggestion or idea?
