no sound in Fedora 8 "PULSEAUDIO: Unable to connect-" using onboard Optical spdif

Legolas327 · 03-02-2008, 12:53 PM

I have read many threads and still not sure what to do. This is a newly built and loaded computer and after upgrades. I have onboard sound MCP55 HDA intel. I am trying to use the spdif optical out. I get nothing. I have an other computer same FD8 OS but it has a audigy z-2 sound card running spdif out (not optical) and it works just fine. If you can help please do. I am out of ideas and not sure what to look for to correct the issue?

Code:

When I run system-config-soundcard I get this in the scsrun.log. First big clue is the "PULSEAUDIO: Unable to connect: Connection refused" Why I don't know?

Help would be greatly appreciated. I'm thinking different driver??? I have read posts about SElinux blocking but did not understand how to check or fix?

My Fedora8 also has no sound... When i playing a music file there's no sound... I tried configure volume control but still no sound. But some times it sounds...zzz

LinuxNewbie999 · 03-02-2008, 11:27 PM

My Fedora 8 also no sound. but some time it sounds...z.zzz I tried configure the volume control but smae thing.. hmmm,, What went wrong??

jfraymondpa · 03-03-2008, 02:13 PM

I get choppy sound with VLC and no sound with XINE trying to play DVDs
Yet I get perfect sound with JUK playing CDs.
Flash and Realplayer clips from the news sites works fine.

Be specific - what kind of music file?

What makes you think this problem is related to OP?

You have been reconfiguring the default av setup - how did you install xine? What did you do to enable DVD playback? Which formats are we talking about? And - what makes you think this problem is related to OP?

@OP: make sure your output is enabled. In gnome, rt-click the volume conrol applet and select "open volume control" - make sure your desired output is checked.

I'm checking your errors and logs. Do you get sound on the other outputs?

LinuxNewbie999 · 03-04-2008, 06:59 AM

Problem fixed after i plugin the headphone. I do not know how it doesn't sounds on laptop itself..

Legolas327 · 03-04-2008, 02:15 PM

Hey Simon! Thanks for looking at this. Which question is addressed to me (Legolas327)?

Simon --

I was running FC 6/KDE, all was working fine. I then upgraded to FC 8/ KDE and lost the sound then. There was no hardware change just the upgrade.

For music, both Ogg and MP3 files, as well as just trying to play Audio CDs.

Xine was installed using Yum. I didn't do anyting to enable DVD, just selected it from Xine. Yes I have been reconfiguring the sound trying to get it to work.

Well anyway it's a moot point now, as I was trying to remove a software package I hosed my system and so I loaded FC 8 /Gnome and I have sound now.
When I have time I'll put in KDE and try again.

Continuing in new thread by OP.

@LinuxNewbie999: how did you get on, that last post was a bit confusing?

lovenemesis · 04-07-2008, 04:54 PM

Check this one I posted, it might be help.

Make sure you put the correct value after "model=", for ALC882 it only has:

3stack-dig 3-jack with SPDIF I/O
6stack-dig 6-jack digital with SPDIF I/O
arima Arima W820Di1
targa Targa T8, MSI-1049 T8
asus-a7j ASUS A7J
asus-a7m ASUS A7M
macpro MacPro support
mbp3 Macbook Pro rev3
imac24 iMac 24'' with jack detection
w2jc ASUS W2JC
auto auto-config reading BIOS (default)

Refer to /usr/share/doc/kernel-doc-2.6.23/Documentation/sound/alsa/ALSA-Configuration.txt for more details.

PS: Kernel 2.6.24 are available for Fedora 8

And I could not find the file referenced below. I did searches but nothing found:

I do have a file called /usr/share/doc/alsa-lib-1.0.15/asoundrc.txt

Well, I forget the default installation won't include kernel-doc.

You can get that reference via:
yum install kernel-doc

It probably nobody knows which option fits you. I am running an ASUS laptop but I have to put "model=lenovo" for my ALC861VD to get audio support.

Just try, there're not too much.

But remember turn the volume to MAX via your mixer provided by the Desktop Environment(e.g. KMixer for KDE).

I strongly suggest you perform an update before all of these:
yum update

rkemp · 07-27-2009, 08:58 PM

I know this is an old thread, but in case someone looking for the solution in Fedora Core 11, try

yum erase kde-settings-pulseaudio xine-lib-pulseaudio
alsa-plugins-pulseaudio

Then run alsamixer from terminal and unmute IEC95B or something similar
