Hello, I have a Dell Latitude CP M233XT laptop. It is currently running FreeBSD 4.5. I am having some problem with the sound drivers. It has a SoundBlaster Pro 3.2 chip. When I am using the "new" PCM drivers I get sound out (i.e. playing mp3s, etc) however the mixer device can't be adjusted. I can "read" the mixer value via just running "mixer" but all of the values come back as "0". The sound volume output is therefore at a constant level and can't be adjusted. Here is what I have in my kernel for this: device pcm device sbc0 at isa? port 0x220 irq 5 drq 1 flags 0x15 device pca0 at isa? port IO_TIMER1 and here is what is found in the dmesg output for this kernel: sbc0: <SoundBlaster Pro> at port 0x220-0x22f irq 5 drq 1 flags 0x15 on isa0 pcm0: <SB DSP 3.02> on sbc0 pca0 at port 0x40 on isa0 When I use the "old" deprecated snd drivers I can adjust the mixer levels but the quality of the sound is not so good. Here is what I have for this kernel build: device snd device sb0 at isa? port 0x220 irq 5 drq 1 device sbxvi0 at isa? drq 5 device sbmidi0 at isa? port 0x330 and the dmesg output: sb0 at port 0x220 irq 5 drq 1 on isa0 snd0: <SoundBlaster Pro 3.2> sb0: driver is using old-style compatability shims Any help getting sound working (specifically the mixer levels) with the new PCM stuff would be greatly appreciated.
