NFORCE 0283 nvsound module : Error : illegal write
Is any dev. aware of this issue? I am running Gentoo Linux 2004.2 with the 2.6.8-r2 kernel. I have sound support (the soundcore.ko module otherwise) built into the kernel statically, as I found out that this resolves the error Arts otherwise generates when using the nvsound module. Incidently it also resolves the nvmixer application manager from crashing with a segfault, which happens if you build sound support as a module.
I can get the module loaded with this configuration (OSS Sound support IS configured as a module BTW, as is ALSA as I am currently using ALSA's intel8x0 module for sound, but it doesn't work either if I leave ALSA support out). My JVC reciever even lights up in Dolby Digital mode, an both analogue and digital outputs are enabled in nvmixer. I just can't play ANY sound whatsoever. And when I do a "cat /usr/kde/3.32/share/sound/pop.wav >> /dev/sound/dsp" I recieve the error "Error : illegal write". Arts can't play sound either, and I see no MIDI mixer in ARTS etiher, something I do see with the intel8x0 ALSA driver. Both /dev/sound/dsp and mixer are there with chmod 660 BTW. And I added alias sound-slot-0 nvsound to /etc/modules.d/aliases and did a source /etc/profile && env-update && modules-update. Still no sound over either the analogue desktop speakers or the digital hookup via the SPDIF to my reciever. Very frustrating.

Re: NFORCE 0283 nvsound module : Error : illegal write
Same issue here:
Using kernel-2.6.7-gentoo-r11 it all works just fine - the module inserts and I get working sound without that annoying hiss inherent in the snd-intel8x0 module.
Using kernel-2.6.8-gentoo-r4 I get this error popping up in KDE:
Sound server fatal error: AudioSubSystem::handleIO: write failed len = -1, can_write = 4096, errno = 29 (Illegal seek)

What's interesting is that lsmod suggests that the module inserts correctly, but that it isn't linked to the other components that use it:

2.6.8-gentoo-r4 compiled for x86_64
I'll use the intel8x0 module for now, but that hissing is doing my nut, so if anyone has any clues why it should suddenly stop working in kernel 2.6.8 I'd be pleased to find out
