ALC898 Audio Stops after a few hours

[E-Chris]

My ALC898 Audio continues to stop working after a few hours. Everything is fine for 2-4 hours and than it just ceases to work unless I reboot. I've tried two different AppleHDA files and two different DSDT implimentations.

 

Has anyone had this problem before and have a possible solution or ideas on where to look to fix the problem?

I use layout id 1 in my DSDT and VoodooHDA 2.8.6 available on here in the AnV signed .kext in DCPI Manager it shows as AudioDevice 0x80868C20, SubDevice 0x1458A002, CodecID 0x10EC0899, Revision 0x0003, Codec Name Realtek ALC898. Now I mainly use my FireWave for surround sound on my video files but my system sounds and music goes through the set of speakers connected to the on-board 898 it works every time I have played them sounds, you may want to give it a try.

I gave up trying to get my ALC898 working and bought one of these:  http://www.amazon.co.uk/Syba-SD-CM-UAUD-USB-Audio-Adaptor/dp/B001MSS6CS
