In looking at cs4236_lib.c, lines 301-307: ver1 = snd_cs4236_ctrl_in(chip, 1); ver2 = snd_cs4236_ext_in(chip, CS4236_VERSION); snd_printdd("CS4236: [0x%lx] C1 (version) = 0x%x, ext = 0x%x\n", cport, ver1, ver2); if (ver1 != ver2) { snd_printk("CS4236+ chip detected, but control port 0x%lx is not valid\n", cport); snd_device_free(card, chip); return -ENODEV; } ...it looks like ver1 and ver2 aren't agreeing. ;) Okay, so I experimented a bit. I commented out (#if 0 ... #endif) the if (ver1 != ver2) {...} block, and added: snd_printk("CS4236: [0x%lx] C1 (version) = 0x%x, ext = 0x%x\n", cport, ver1, ver2); ...recompiled, reinstalled... and then: `modprobe snd-cs4236 port=0x530 cport=0x538 isapnp=0 dma1=1 dma2=0 irq=5` results in: /dev/dsp, /dev/audio, /dev/snd/* all appear, laptop speakers click once (as before), followed quickly by a , and we're on our way... almost. my shorthand dmesg (printk) shows me that the driver was unloading because 0xFF did not equal 0xE8. (I'm going from memory here. I'm positive that the value of "ver1" was 0xFF -- not quite sure about "ver2", but it's close. ..it definitely wasn't 0xFF (obviously!) which is why the driver load aborted). cat /proc/asound/cards reports card 0 is a CS4237B at IRQ 5, DMA 1,0 in KDE, kmix loads and allows me to play with buttons/sliders - I can get CD audio to play out the laptop speakers, but other audio does not work. xmms will load an mp3 file, but when I click the play button, the display shows 0:00, and nothing plays. No sound, and the "progress bar" and "time remaining" stay at 0. in terminal, `alsamixer` results in a segmentation fault. ..incidentally, in this "hacked" module, it doesn't really matter what (reasonable) value I specify for cport= in /etc/modprobe.conf (0x538, 0x120, 0x110 ...). The result is the same. kmix allows some adjustment, cd audio plays, no other sound, and alsamixer seg faults. No doubt, if I were to work at it, I could generate a kernel panic with the right value... ;) ====================================================================== ---------------------------------------------------------------------- rlrevell - 01-23-06 01:36 ---------------------------------------------------------------------- I guess it's CONFIG_PNP ---------------------------------------------------------------------- briand - 01-23-06 02:15 ---------------------------------------------------------------------- ah, no.. I have (had?) a CONFIG_PNP verb, and it was set to 'yes' ...looks like it's something that was added after 2.6.9 ...I'm installing 2.6.15.1, and I'll turn on CONFIG_PNPBIOS in that kernel build, and report back.
