I just updated from an old version 6.0.8721.1 to the latest 6.0.8911.1. I only use it for the Dolby Digital Live 5.1 encoding and the old version worked well except for occasional blue screens. The speaker assignments for 5.1 were fine.
When I updated to 8911, the speaker assignments are screwed up. If I configure a client to output 5.1 (which worked fine with the older driver), the FR,FL,C,SW work fine but SR and SL sounds come through FR and FL and nothing in SR and SL. If I configure the client to output 7.1, the SR and SL in that output correctly go to SR and SL speakers. The RR and RL are dropped, as expected. Why is the channel to speaker assignment different in the latest driver while it worked fine in the older driver?
Is this a configuration issue somewhere or is there a bug in the driver?
PS: I also tried DTS in the old driver and it works. But in the new driver, only Dolby Digital LIve option is present. I used the tweaker as suggested to create a HD config file. The DTS option is now available but using the Realtek HD manager to set it to DTS results in a freeze of the manager. In the Sound devices section, I can neither assign DDL or DTS Connect, I get a message saying the device is not capable of it. if I remove the weaker generated file, the DDL 5.1 works but with those speaker assignments screwed up.
