Ivan, Have u tried playing sound/cd as root? If you've just tried from a normal user account check to see if you're a member of the audio group by typing:
groups in a terminal. If you are not a member of the audio group then addyourself. Edit the /etc/group file and add yourself. Check permissions on /dev/dsp and most probably /cdrom as well. Make sure ur normal user can access them. That's about all I can think of.

Dear All I'm running Debian Woody on an IBM Thinkpad A31p. Everything is working fine, except sound. I *think* the problem is incorrect parameters to the relevant kernel modules, but (a) I might be wrong and (b) I don't know how to set the parameters. Any pointers on these two - or any other helpful info - would be gratefully received. The sound card is an Intel Corp. 82801CA/CAM AC'97 Audio (Analog Devices AD1881A). I had read (e.g. at the linux-laptop site) that Thinkpad sound, and this card specifically, was OK on Linux, with the i810 and mpu401 modules. I have also got into trouble trying to recompile the kernel to set up ALSA, so I'd rather avoid that for now. Installing Debian, I made sure the following sound driver modules were checked: ac97_codec i810_audio mpu401 sound soundcore I gave no parameters as I wasn't aware of the need for any at the time. Having installed Debian sound was just not working. For example, cdcd would happily play my CDs - silently. (At the moment only root has access to certain devices - e.g. audio, write access to hda1 - but that's a separate issue.) There follows all the information I could find on my setup. From the IO/IRQ discrepancy shown between the boot messags and The Other OS, I would guess that I need to add parameters to some/all of the modules. But which and how (and how to translate the Windows figures into something useful) I have no idea. - sndconfig correctly identifies the sound card but can't config it. - lsmod includes four of the modules, but not i810_audio: Module Size Used by Not tainted mpu401 18784 0 (unused) sound 52876 0 [mpu401] ac97_codec 9568 0 soundcore 3236 2 [sound] - /etc/modules does not include ac97_codec, sound or soundcore, but does include i810_audio and mpu401 - There is nothing about sound in /etc/modules.conf - The following is from dmesg (boot messages), which seems to imply that something is going wrong: ... Intel 810 + AC97 Audio, version 0.21, 10:28:09 Apr 14 2002 PCI: Found IRQ 11 for device 00:1f.5 PCI: Sharing IRQ 11 with 00:1f.3 PCI: Sharing IRQ 11 with 00:1f.6 PCI: Sharing IRQ 11 with 02:00.1 PCI: Setting latency timer of device 00:1f.5 to 64 i810: Intel ICH3 found at IO 0x18c0 and 0x1c00, IRQ 11 i810_audio: Audio Controller supports 6 channels. ac97_codec: AC97 Audio codec, id: 0x4144:0x5348 (Analog Devices AD1881A) i810_audio: AC'97 codec 0 Unable to map surround DAC's (or DAC's not present), total channels = 2 ac97_codec: AC97 Modem codec, id: 0x5349:0x4c27 (Unknown) i810_audio: timed out waiting for codec 1 analog ready. ... - I got the following details from The Other OS on my machine (Windows 2000 'Pro'). Note that the I/O and IRQs are different from those above (Linux seems to put just about everything on IRQ 11; Windows seems to put just about everything on IRQ 9). I couldn't find DMA figures specifically for the sound device, only for this 'DMA controller'. I couldn't find any DMA16 or MPU figures at all. 1. sound config info Location: PCI bus 0, device 31, function 5 Driver: SoundMAX Integrated Digital Audio 5.12.1.3039 Provider: Analod Devices Resources: input/output range: 1C00 - 1CFF input/output range: 18C0 - 18FF Interrupt Request: 09 2.

Questions: - Is it an IO/IRQ problem, and if so - what other info do I need (e.g. dma, mpu) and how do I get it? - how do I add module parameters? - If not: - what else might it be? - where do I need to look? (I'd rather avoid alsa/kernel stuff until I've exhausted this track) Best wishes Ivan -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
