Esound comes with a program esddsp that can, in some cases, make these programs use esound instead of /dev/dsp. It doesn't always work though. Also, if you can convince the program to produce output on stdout, you can pipe it to esdcat (with sox in between if necessary) Esound basically acts as a mixer - taking input from the user programs, mixing it together and feeding it to /dev/dsp. In the ALSA docs it mentions a feature like this as well. However, it would only work for progs written to use alsa, and it hasn't actually been implimented yet AFAIK. - -- finger for PGP public key. -BEGIN PGP SIGNATURE- Version: 2.6.3ia Charset: noconv iQCVAwUBOAQVHL7M/9WKZLW5AQHnOwQAnN24o3+gcf8Q0cBgPvkYzWR+qJ8/uCTo r8LtqMrkYw+D4gaj7Ycp+H9qNfbs5F5ChZEsYFUFhs0PX8Of2aSFt9Q7gakiOtsw JTeR7ULsopFVEaXbfxTApEJjaAYCxeMwr/YrmOAZw9V8bop1waBU5Vk4HMncuSIG M6lGHbYAZrc= =LCyZ -END PGP SIGNATURE-

Rob - I use OSS the commercial version as my sound driver and I also run esound from my Gnome desktop. It was purely an accident but I found that all of the Gnome system sounds are output via esound and I can use the CD player from XMCD to have music at the same time. I also noticed that my microphone is active too, since I was getting some bad feedback noise. I was able to use the Gnome mixer to control all of this, so that it works OK. The wierd thing is that I have to log in and start both OSS and Esound as root, in an Xterm, in Gnome; then log out and log back in as a user to have it work in a regular session. If any one knows how to get them both running at boot up I would appreciate some help. I have only been experimenting with sounds for a month or so. Thanks. BTW I run ICEGnome not enlightenment and I have a Gnome taskbar hidden at the top of the screen and a ICE debian taskbar hidden at the bottom of the screen.

Re: Multiple accesses to /dev/dsp
I knew about Esound, but I need something that: - Split input (microphone, etc) to multiple processes - Works with existing programs (eg. Quake) This is probably a wishlist item for ALSA, but I was wondering if anyone already knew on a *kernel* patch that does the mixing at the /dev/dsp level.

Re: Multiple accesses to /dev/dsp
i may be wrong but i think the esound daemon does this, not though in the way you say. i believe, apps send the output of the audio to the daemon and the daemon opens /dev/dsp and outputs it there. any number of apps can talk to the daemon and the daemon can/will output sound from multiple sources. i've never used it just read bits about it, i could be wrong :) nate [mailto:[EMAIL PROTECTED] ]-- Linux System Administrator http://www.firetrail.com/ Firetrail Internet Services Limited http://www.aphroland.org/ Everett, WA 425-348-7336http://www.linuxpowered.net/ Powered By:http://comedy.aphroland.org/ Debian 2.1 Linux 2.0.36 SMPhttp://yahoo.aphroland.org/ -[mailto:[EMAIL PROTECTED] ]-- On Tue, 12 Oct 1999, Dwayne C .
