I've finally found this to be caused by a problem in the Maestro2E audio driver: My laptop has 512MB RAM, and when the DMA buffers are allocated beyond the 256MB limit the audio chip is unable to access them. (This is the snd-card-es1968 ALSA driver.) I had to make a simple (to edit, not to find) code change in lowlevel/pci/es1968.c to get it working, as the allocation schema is not configurable by parameters. This is on SuSE 7.0, ALSA 0.5.8b, es1968 driver. I believe any machine with more than 256MB RAM and a Maestro2E sound chip set must be affected. How/where can I find out if this is fixed in later ALSA versions, and if not, how do I commit this back? /Lennart -----Ursprungligt meddelande----- Från: Lenz Grimmer [mailto:grimmer@suse.de] Skickat: den 24 november 2000 11:07 Till: suse-linux-e@suse.com Ämne: Re: [SLE] artsd of KDE2 does not start Hi, On Thu, Nov 23, Lennart Börjeson wrote:
I updated my SuSE 7.0 to KDE2 last week, but I'm unable to get any sound application running. They all complain artsd is not running, and it in turn complains:
Error while initializing the sound driver: device /dev/dsp can't be opened (Operation not permitted)
...and now I'm stuck... I tried resetting and reinstalling the sound card in YaST2, and once, just once, this helped, but I've not been able to repeat this.
It looks like you do not have the proper permissions to access the audio devive /dev/dsp. Did you add your account to the group "audio"?
