Hey all, i have skype and everytime i try to call someone i get "problem with sound device". Now the skype forums arnt too helpful but basically what it narrows down to is something is using my sound (/dev/dsp).

Now ive had this problem before when i was running Kmix and fixed it by killing it in the process/icon bar.

However i cant see anything visually using the sound.

Any suggestions?


Skype also says:

/dev/dsp-1: Device or resource busy

lsof | grep /dev/dsp

This will list any programs that are currently using your dsp device. You can react accordingly.

I'm having the exact same problem.
/dev/dsp-1: Device or resource busy

It seems to be a bit random. It seems to happen less often when the far end hangs up, and more often when I hangup. I had it with version 20, and downgraded to 17. Same thing.

lsof | grep dsp

skype 16738 jcouper 39u CHR 14,3 5382 /dev/dsp

So, the process using it is skype itself... so it's an internal skype bug... it fails to free the device, and the attempts to re-claim it, and fails because it already has it. Exiting skype frees the lock on the dev, and a call made after a restart will work normally.

I'm on FC4. Everything else seems to work OK. The sound quality seems to be just fine. Just this silly /dev/dsp locking problem! Is there a way to formally raise bugs to skype?

Ooops. Correction. It happened with It does NOT seem to happen with the earlier version! So, if this is annoying you, downgrade to and wait for a fix by Skype.

I have seen that maybe you're using adsp instead dsp, /dev/dsp is usually a link to /dev/dsp0 or could be /dev/adsp, in my case (slack 10.2) it pointer to /dev/dsp0 and my problem is that i want to be able to play other media files while i'm using skype, i don't know how to solve this problem, i have another computer that runs slack 10.1 and use udev system, so i figure that making the link of /dev/dsp to /dev/sound/adsp works fine, but as i'm not using udev in this laptop i'm not able to link /dev/adsp to /dev/dsp. I don't know if it has to be with that or it has to be with the sound card.

I hope this can help you friends, try to use adsp instead of dsp.
