When I play any audio CD the music play back stutters. I have an integrated sound motherboard. The playback software/device(?) is called ESS Audiodrive. When I ran DXDiag and tested this under the music tab the DXdiag locked up (had to quit DXdiag with task manager). Previous times with DXDiag this test worked fine. Am using WMP 9 recently downloaded and installed. I have attached the DX info file (without running the Music tab ESS Audiodrive test). If there is any other info needed, please reply.
