Greetings, We just recieved a number of new systems in for FreeBSD desktop usage that have Intel TC430HX motherboards with on-board sound. I'm using Luigi's sound drivers from 09/08. Playing audio CD's is fine and cat'ing a test au file to dev/audio works. Using RealAudio only works in 8 bit mode, 16 bit gives a "can't open device error". RealAudio in 8 bit mode is shakey at best and gives me a lot of errors: Sep 19 12:26:12 psv /kernel: SNDCTL_DSP_SETFRAGMENT 0x0003000c Sep 19 12:26:12 psv /kernel: SNDCTL_DSP_SUBDIVIDE yet unimplemented Sep 19 12:26:12 psv /kernel: dsp write channels 1 Sep 19 12:26:12 psv /kernel: dsp reset Sep 19 12:26:17 psv /kernel: SNDCTL_DSP_SETFRAGMENT 0x0003000c Sep 19 12:26:18 psv /kernel: SNDCTL_DSP_SUBDIVIDE yet unimplemented Sep 19 12:26:18 psv /kernel: dsp write channels 1 Sep 19 12:26:44 psv /kernel: dsp sync The integrated sound info from Intel's specs is : "a Yamaha* OPL3-SA audio CODEC is integrated onto the motherboard. The OPL3-SA provides 16-bit stereo,Sound Blaster* Pro and Windows* Sound System compatibility and full-duplex capabilities. An optional Yamaha OPL4-ML audio CODEC provides FM and wavetable synthesis." The BIOS audio configuration is as follows: SB Port Base 220h , WSS Port Base 530h, MPU Port Base 330h, WSS Interrupt IRQ 10 SB/MPU Interrupt IRQ 7, WSS Play DMA Channel 0, SB Play/WSS Capture DMA Channel 1, FM Synthesizer Port Status 388h My kernel configuration (2.2.2-RELEASE) is: controller pnp0 device pcm0 at isa ? port 0x530 tty irq 10 drq 0 flags 0x13 vector pcmintr Dmesg output is: Probing for PnP devices: No Plug-n-Play devices were found Probing for devices on the ISA bus: sc0 at 0x60-0x6f irq 1 on motherboard sc0: VGA color <16 virtual consoles, flags=0x0> pcm0 at 0x530 irq 10 drq 0 mem 0x0 flags 0x13 en 1 confl 0 mss_detect - chip revision 0x0a mss_detect() - step I mss_detect() - Detected CS4231 pcm0 at 0x530 irq 10 drq 0 flags 0xa213 on isa mss_attach <mss>0 at 0x530 irq 10 dma 0:3 flags 0xa213 cat /dev/sndstat: FreeBSD Sound Driver Sep 19 1997 09:34:05 Installed devices: pcm0: <mss> at 0x530 irq 10 dma 0:3 Am I missing anything in the configuration, or is this on-board sound just not supported fully yet ? I'd appreciate any suggestions. Thanks. Greg Rowe
