acidos77 Posted September 20, 2013 Share Posted September 20, 2013 Mobo: DSDT-GA-Z68X-UD3H-B3 I'm using DSDT and ALC889 driver and getting the following errors: Sep 20 15:06:37 liondev kernel[0]: Sound assertion - Command/Response TIMED OUT and ( kRequestStateMatch == fCodecRequest->state = 2 ), fCodecRequest->command->codec: -549449031168, fCodecRequest->command->verb: 0xFFF, fPoweredDown: 0Sep 20 15:06:37 liondev kernel[0]: Sound assertion in AppleHDAController at line 5097 Sep 20 15:06:37 liondev kernel[0]: Sound assertion in AppleHDAController at line 5098 Sep 20 15:06:37 liondev kernel[0]: Sound assertion in AppleHDAController at line 8276 Sep 20 15:06:38 liondev kernel[0]: Sound assertion - Command/Response TIMED OUT and ( kRequestStateMatch == fCodecRequest->state = 2 ), fCodecRequest->command->codec: -549449030144, fCodecRequest->command->verb: 0xFFF, fPoweredDown: 0 Sep 20 15:06:38 liondev kernel[0]: Sound assertion in AppleHDAController at line 5097 Sep 20 15:06:38 liondev kernel[0]: Sound assertion in AppleHDAController at line 5098 Sep 20 15:06:38 liondev kernel[0]: Sound assertion in AppleHDAController at line 8276 Those errors appear when I try to playback sound.

acidos77 Posted September 21, 2013 Author Share Posted September 21, 2013 I solved the problem with installing ALC8xxHDA and HDAEnabler from GA-Z68X-UD3H-B3 pack. Also upgraded bios to F12, not sure if this is related though. No more assertions. Link to comment Share on other sites More sharing options...
