audacious audacity trouble

[Master of Reality]

I just installed audacity on slackware, with all the requirements and such i think. But when i start it i get:

There was an error initializing the audio i/o layer.
You will not be able to play or record audio.

Error: Host error.

I tried running $ aoss audacity
and it didnt give methat error, but gave me this when i tried to record

Error while opening sound device. Please check the input device settings and the project sample rate.

and on the command line it says:

PaHost_OpenStream: could not open /dev/dsp for O_RDONLY
PaHost_OpenStream: ERROR - result = -10000

The permissions on /dev/dsp0 is 666 and /dev/dsp does link to /dev/dsp0.
Artsd is not running, and no other sound programs are either.
lsof doesnt show anything using /dev/dsp either

Any ideas what im missing to get audacity working?

Who owns /dev/dsp?

[Master of Reality]

the ownership of /dev/dsp is root.root and the ownership of /dev/dsp0 is root.audio
and /dev/dsp is a link to /dev/dsp0

[lakerdonald]

Change them both to *.audio, and make sure you're in the audio group.

I still get the same error after doing that

You'll need to either:
1. restart X, so that all xterms are opened with the right permissions
2. run

su - username

from an existing xterm
3. login through a VT

...I think you're a bit confused.

No. You need to log back in so that permissions get updated for the current shell.

I googled this - see if this info is useful to you.

If you should happen to be using KDE then open:

'KDE Control Center' -> 'Sound & Multimedia' -> 'Sound System'

'General' tab: turn on 'Auto-Suspend' and set for 1 second (or whatever)

'Hardware' tab: double-check all settings...

Hope this is helpful...
