Pulseaudio error in ubuntu 8.10

maiden2 · 11-20-2008, 12:37 AM

Hello everybody,

I declare in advance not to possess specific knowledge around the "audio" features of my Ubuntu 8.10 new PC, but from a month ago, a lot of times I was unable to play audio files due to unknown System Problems: yesterday, testing some diagnostic software like "gnome-system-log", I found these logs on my "users logs" section:

Code:

Nov 20 00:32:32 hal-9000 pulseaudio[6424]: protocol-esound.c: pulsecore/protocol-esound.c: Failed to create sink input.
Nov 20 00:43:29 hal-9000 pulseaudio[6424]: protocol-esound.c: pulsecore/protocol-esound.c: Failed to create sink input.

Nov 20 01:40:08 hal-9000 pulseaudio[6424]: protocol-esound.c: pulsecore/protocol-esound.c: Failed to create sink input.
Nov 20 01:50:52 hal-9000 pulseaudio[6424]: protocol-esound.c: pulsecore/protocol-esound.c: Failed to create sink input.

Could you suggest me some solution? How should I solve this audio configuration problem? I specify that thaat this error is encuntered because of a configuration conflict or something like that because I didn't activate any pulseaudio resource directly.

My config is:
SO: Ubuntu "Intrepid"
CPU 0: Intel Core 2 duo E 4500 @ 2.20GHz
CPU 1: Intel Core 2 duo E 4500 @ 2.20GHz
Kernel: 2.6.27-8-generic
GNOME 2.24.1
Free HDD space available: 155 GB

Well I'm certainly no expert but I had audio problems that stemmed from having pulseaudio selected in the "sessions" tab. Once I unchecked that box my audio problems disappeared. Found under system/preferences/session. To date I have had no reason I'm aware of to research the problem further. Hope it helps.

I appreciate that it is not good form to recommend looking at a link in another forum but there we are.

If you search the Mulimedia and Video section of the Ubuntu forums you will find that pulseaudio is a very popular topic.

Here is one which may be useful:

Also look at the Sound Settings section in here.

For reference only:

Had similar errors and behaviour.

Turned out my KVM virtual machine was the issue.
I removed the sound card from within the virt-manager configuration and the problem was solved.
I'm sure there is a work around but I don't use sound in the client so it's fine for me.
