I merged your codes into the cvs. The codes are almost identical except for small bugfixes, re-indentation, and replacement of debug printing. To be sure, the old dsp image is still chosen unless CONFIG_SND_CS46XX_NEW_DSP is set to yes. For compiling the new dsp image, please remove the comments in alsa-driver/pci/cs46xx/Makefile. The driver seems working on TerraTec DMX XFire. The status is: - OK: The first codec - OK: SPDIF playback (audio) - NG: SPDIF AC3 (non-audio) - NG: The secondary codec, not detected. Anyway, thanks for your work! Please send patches againt cvs if you modify the driver more, so that I can commit it soon. ciao, Takashi ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
