Hi Chris Unfortunately, it didn't. And I also have to do it everytime it restarts. I'm thinking about doing a init script to do it for me...

Re: [gentoo-user] Can't get ALSA OSS Emulation to work
I can only suggest you look carefully at /dev/dsp - it should i think be a link to /dev/sound/dsp. Then look at the permissions on /dev/sound/dsp - they should be: crw-rw 1 root audio 14, 3 Jan 1 1970 /dev/sound/dsp and the user trying to run the errant program should be in the audio group. (and re-logged in if you add them as a result of this message, ie adding a user to a group does not take effect until they log in again. Unfortunately this can mean logging oput of X and back in again) You can check if user is in the audio group with: id user On Tue, 16 Aug 2005 20:09:15 -0300 Raphael Melo de Oliveira Bastos Sales wrote: Thanks for the attention.

I haven't been reading this list in depth lately. As I say, I think the capabilities provided here by the Gentoo devs look good, but I get the feeling there maybe wasn't so much thought given to multiple sound card systems. For instance, if I have an expensive sound card in a system which also has an on-board sound chip, then maybe I want Alsa support for both devices, but OSS support only for the second card. Game audio, etc., goes there while recording studio audio goes through the high-end card using Jack. This allows me to run Jack through the first card while I run OSS through the second. The first card goes to external D/A A/D converters. The OSS audio goes out of the machine as analog and into an external A/D to get resynced with Jack. How do I do this? (I.e. - I can do it easily with the sort of configuration I presented earlier.) Thanks, Mark -- gentoo-user@gentoo.org mailing list

Re: [gentoo-user] Can't get ALSA OSS Emulation to work
I feel really stupid. It wasn't the permission, but to get both quake and enemy territory to play , they have to be given direct access to the sound hardware. To do that, you must go to /proc/asound/cardX/pcm0p/ and add the following line to the oss file in this directory. Something like this: echo q3demo.x86 0 0 direct /proc/asound/card0/pcm0p/oss I was putting just q3demo, which is actually just a script to call the game, not the program that would use the sound. And that's why it didn't work. Thanks for the help. I'll try to have more attention to this type of details in the future. Thanks again Nick and Mark ;) -- gentoo-user@gentoo.org mailing list
