Hello,=20 I am trying to get the nm256 driver to work on a Dell Inspiron 3500 = laptop. It seems I am not alone with this issue (see posts from Ted To = 2007/03/05 and Matt Gushee 2006/10/23). Using force_ac97=3D1 I can get everything = to load, but an attempt to play a wav file gives the following error = message: Lappy366:~# aplay /home/family/wavs/curly.wav Playing WAVE '/home/family/wavs/curly.wav' : Signed 16 bit Little = Endian, Rate 44100 Hz, Stereo aplay: pcm_write:1268: write error: Input/output error I am running a 2.6.18 kernel as provided by the Debian etch distribution = (as of 4/07). The ALSA driver version is 1.0.12rc1. lspci | grep audio = reports: 01:00.1 Multimedia audio controller: Neomagic Corporation NM2200 = [MagicMedia 256AV Audio] (rev 12) I have also tried loading snd-cs4232 and snd-ad1848, as suggested by = various Googlings, but I always get "No such device" in response. My /etc/modprobe.conf file has one line: options snd_nm256 force_ac97=3D1=20 lsmod | grep snd yields: snd_opl3_lib 9920 0 snd_hwdep 8836 1 snd_opl3_lib snd_cs4231_lib 23232 0 snd_mpu401_uart 8064 0 snd_rawmidi 22560 1 snd_mpu401_uart snd_seq_device 7820 2 snd_opl3_lib,snd_rawmidi snd_nm256 67680 1 snd_ac97_codec 83104 1 snd_nm256 snd_ac97_bus 2400 1 snd_ac97_codec snd_pcm 68676 3 snd_cs4231_lib,snd_nm256,snd_ac97_codec snd_timer 20996 3 snd_opl3_lib,snd_cs4231_lib,snd_pcm snd_page_alloc 9640 2 snd_cs4231_lib,snd_pcm snd 47012 12 snd_opl3_lib,snd_hwdep,snd_cs4231_lib,snd_mpu401_uart,snd_rawmidi,snd_seq= _de vice,snd_nm256,snd_ac97_codec,snd_pcm,snd_timer soundcore 9248 1 snd The relevant section of dmesg is: <snip> parport: PnPBIOS parport detected. parport0: PC-style at 0x378 (0x778), irq 7, dma 3 [PCSPP,TRISTATE,COMPAT,ECP,DMA] agpgart: Detected an Intel 440BX Chipset. agpgart: AGP aperture is 64M @ 0xe0000000 ACPI: PCI Interrupt Link [LNKB] enabled at IRQ 11 ACPI: PCI Interrupt 0000:01:00.1[B] -> Link [LNKB] -> GSI 11 (level, = low) -> IRQ 11 nm256: found card signature in video RAM: 0x27ec00 nm256: Mapping port 1 from 0x2709a0 - 0x27ec00 input: ImExPS/2 Logitech Wheel Mouse as /class/input/input2 ACPI: PCI Interrupt 0000:01:00.0[A] -> Link [LNKA] -> GSI 10 (level, = low) -> IRQ 10 neofb: mapped io at ccc80000 Autodetected internal display Panel is a 1024x768 color TFT display neofb: frame buffer in use neofb: probe of 0000:01:00.0 failed with error -16 piix4_smbus 0000:00:07.3: Found 0000:00:07.3 device PCI: Enabling device 0000:06:00.0 (0000 -> 0003) ACPI: PCI Interrupt 0000:06:00.0[A] -> Link [LNKA] -> GSI 10 (level, = low) -> IRQ 10 3c59x: Donald Becker and others. www.scyld.com/network/vortex.html 0000:06:00.0: 3Com PCI 3CCFE575BT Cyclone CardBus at cc820000.

I have tried the other patches like reset_workaround, reset_workaround2, and vaio_hack, just to see if they might help, but no luck. I am more than willing to try things out on my hardware to help solve this problem, if anyone wants to tackle this.=20 Thanks, Jabez=20 |
