Hello ALSA developers, Thank You Mr. Sjostrand and Takashisan for your helpful replies! In order to avoid confusion with other changes that are certainly in cvs since the rc3 release I uncommented the CONFIG_SND_CS46XX_NEW_DSP definition in pci/cs46xx/Makefile instead of checking out a completely new source tree. This lead me to a problem with an undefined symbol for snprintf in snd-cs46xx.o (I'm running a 2.4.2 kernel) which I worked around with a hack to dsp_spos_scb_lib.c in alsa-kernel/pci/cs46xx: #define snprintf(buf,size,fmt,args) sprintf(buf,fmt,args) I found a similar hack in include/asound.h for vsnprintf(), however adding the above line to this header didn't eliminate the undefined symbol in snd-cs46xx.o. Apparently asound.h doesn't make in into dsp_spos_scb_lib.c. After getting around my library deficiencies I was able to load the snd-cs46xx module and can report that I no longer have the syslogging problem I was experiencing with xmms playing mpeg video (playing internet streaming audio and local mp3 and wav sound files had never been a problem). My hardware platform is the integrated sound in an IBM Thinkpad T-20. It may just be a subjective reaction to getting this new build running, but I also believe that streaming audio sounds crisper and clearer with this new driver. Thank You Once Again for your help! I stand ready to supply any other configuration information or provide any other meager assistance of which I'm capable. John E.
