Usually cheap soundcard got a cheap design as result of a tiny bugdet, so just dont expect to much from the analog part's. Actually I got a Hercules GameTheater XP 6.1, when volume is over about a ~80% the output is sometimes distorcionated, but I believe that's something we cant do anything about in the driver. Limit some volume control's in the driver dont feel like a coherent solution. The card is still usable, I really dont expect to better quality on analog output with this soundcard. >ALSA ../alsa-kernel/core/pcm_lib.c:123: Unexpected hw_pointer value (stream = 0, delta: -512, max jitter = 8192): wrong interrupt acknowledge? >ALSA ../alsa-kernel/core/pcm_lib.c:123: Unexpected hw_pointer value (stream = 0, delta: -512, max jitter = 8192): wrong interrupt acknowledge? >ALSA ../alsa-kernel/core/pcm_lib.c:123: Unexpected hw_pointer value (stream = 0, delta: -512, max jitter = 8192): wrong interrupt acknowledge? > > Feel like theese messages should not be there, could be a bug in cs46xx driver. >I am wondering about the status, as there is still this comment in cs64xx_lib.c: >--------------------------- > /* CD mute change ? */ > > /* Benny: this hack dont seems to make any sense to me, at least on the >Game Theater XP, > Turning of the amplifier just make the PCM sound very distorcionated. is this really needed ???????????????? > */ >--------------------------- > > > Should only matter if you unmute the analog CD input, and with the new DSP code it dont matter at all. /Benny ------------------------------------------------------- This SF.NET email is sponsored by: Thawte.com Understand how to protect your customers personal information by implementing SSL on your Apache Web Server.
