I use the alsaconfig script and it writes in the modules.conf file the following: # Alsa sound support. # Warning: please don't modify comments over aliases 'snd-card-#' alias char-major-116 snd alias char-major-14 off options snd snd_cards_limit=1 snd_major=116 options snd-cs4236 snd_cport=0x538 snd_dma1=1 snd_dma2=0 snd_enable=1 snd_fm_port=0x388 snd_index=0 snd_irq=5 snd_isapnp=0 snd_mpu_irq=9 snd_mpu_port=0x330 snd_port=0x530 snd_sb_port=0x220 # --- END: Generated by ALSACONF, do not edit. --- # uniq.virtual:Sound card alias snd-card-0 snd-cs4236 # YaST2: sound system dependent part # alias sound-slot-0 snd-card-0 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-11 snd-mixer-oss alias sound-service-0-12 snd-pcm-oss The port and irq parameters mightr be different in your computer. I have the idea the control port nr is not correct in your case. You should check that ( if you have windows on the same machine you can find it there) When I use ALSA for my cs4236 everything works ( gamix and alsamixer as well) but I am not too happy with the quality, but that might be due to my hardware. Using a cs3232 kernel driver gives better sound but is lacking most of the mixer control as it is not aware of the control port Alsa 0.9 is much better in my case than alsa 0.5 in particular the alsaconfig script is very useful regards Arie |
