I have a problem with slackware9.1/alsa sound and enemy-territory, sound not start in game but sound is ok in all apps !!!
------- sound initialization -------
/dev/dsp: Input/output error
Could not mmap /dev/dsp
------------------------------------
And I find that this can be a future problem since alsa goes to be part of kernel of linux 2.6.
Sorry, but i brazilian and my english is bad 
need help for listen kabuums in ET !!!
Thanks
Run lsmod and make sure snd-pcm-oss is listed. Also make sure you have the neccessary device nodes. They should have been created when you installed Alsa. The DSP devices should all have major number 14 and minor numbers 3, 19, 35, and 51 for dsp0, dsp1, dsp2, and dsp3 respectively.
I did not only understand what I have that to make so that it functions! :suspicious:
I have no idea what you just said. I donāt think Iāll be able to help you, since neither of seem to be able to understand each other. I donāt think your problem is ET specific, though. Iām sure there are portuguese speaking Linux forums where you can find an answer. Your problem is most likely related to the fact that Quake 3 engine based games are not capable of using Alsa directly, and require that OSS emulation be installed.
emulation oss is ok and running !
the problem must be of the engine of quake 3ā¦ :eek:
Thanks and forgives my English.
:banghead:
I am also experiencing this problem, using ALSA CVS and linux 2.4.23. I get the same error:
------- sound initialization -------
/dev/dsp: Input/output error
Could not mmap /dev/dsp
------------------------------------
And I have tried echo āet.x86 0 0 Directā > /proc/asound/card0/pcm0p/oss and the ādisableā version of the former command as well, to no effect.

I am using ET 1.02. I am using the intel8x0 onboard sound for my Epox 8RDA+ nForce2 Ultra400 motherboard.
Would really appreciate it if someone could help me. Canāt wait to get back to playing ET.
Check your kernel log (e.g. run dmesg) to see if ALSA was kind enough to output anything useful. In theory, mmap() shouldnāt fail unless the card isnāt capable of being fed interleaved audio samples via DMA (and almost every sound card is; i8x0 sound, despite being evil, is no exception.) Do any other applications that use mmap()d around (mostly games) work? Does anything work?
Another thing you can try is using aoss if youāre not (aoss is a runtime wrapper library that tries to emulate OSS in userspace instead of kernel space), or vice-versa.
Failing all that, you can try editing core/oss/pcm_oss.c in alsa-driverās source, changing the #if 0 containing #define OSS_DEBUG to #if 1, recompiling/reinserting the relevant bits of alsa-driver, and trying ET again (some debugging spew should end up in the kernel log that may help you or someone on the forum figure out whatās going wrong.)
Meh. :moo:
