Sound & audio pcee needs to be installed when trying to enable dolby home theater i saw a few posts about enabling dolby home theater within my realtek driver. Everything is working fine except that the upgrading process completely removed the Dolby Home Theatre application and its drivers and automatically installed the Realtek high definition drivers, after I found out about it, I tried some tips I found online, this is what I did: Downloaded the audio drivers from the Acer website. Disable driver signature enforcement after each installation step again! Now I will test the audio. Edit 12:31 pm: Installation worked flawless. I have the same Problem I and am trying the above method now. I ran 'sudo modprobe snd-cmipci' to make sure that the module is running.Easy Way to Install Dolby Home Theater v4 In Windows 7,8,10. I didn't see 'cmi8738' as a chipset option when I was performing the modprobe snd- command, but I followed instructions further in the guide to compile the module, and the program said that 'cmipci' is the module used for cmi87x8 chipsets.

The system recognizes that the card is present, after I ran a few terminal commands as instructed in the the sticky thread, 'Comprehensive Sound Problem Solutions Guide'. I had installed a TurtleBeach Montego DDL, with the CMI8738 chipset and performed a fresh installation of 8.04. When I press play for a song in Rhythmbox, the song does not play. On the sound mixer, PCM is muted, and attempting to unmute it doesn't work. I am unable to get any sound from any application.
