Qt4 install .. now I have sound problems ?

orbit · 10-09-2007, 07:30 AM

Hi all,

Today on my Slack12 system, I installed qt4.3.1 as a required dependency for the new version of smplayer-0.5.42; now I have no sound when I login to KDE?

[I get a "no sound server found" error].

Has anyone else experienced this problem at all?

Any ideas from anyone where I need to look to resolve this? (arts,alsa)?

Any help appreciated, thanks in advance

Cheers

Look at the symlink for qt, if you installed qt4, it may have overwritten the link to qt3.

Hi manwichmakesameal,

Thanks for the quick response

I have found a ~qt link to qt-3.3.8 in /usr/lib/ .

Do you mean that I should re-link that from /usr/lib/qt-3.3.8 (which is still installed by the way) to /opt/qt4/ ?

If that is not what you mean, where is the link you are talking about? and where should it (now) link to?

Cheers

In Slack12, the link should be /usr/lib/qt linking to /usr/lib/qt-3.*, so you're alright there. Have you tried running alsaconf and see if it detects your card? I have qt4 installed, and it didn't bother my sound at all. Did you have to install anything else as a dependency?

Hi manwichmakesameal,

Yes, smplayer also required wengophone as another dependency.

Here is what I have done so far:

1. In root terminal, ran alsaconf (soundcard detects fine).
restart (>> no sound).
2. uninstalled arts, recompiled from slackbuild and re-installed.
restart (>> no sound).
3. linked /usr/lib/~qt >>from /usr/lib/qt-3.3.8 >>to /opt/qt4/
restart (>> no sound).
4. uninstalled alsa-libs, alsa-utils and alsa-oss, then reinstalled
restart (>> no sound).
5. I have run alsamixer and kmix, both report that sound levels and switches are correct.
restart (>> no sound).

N.B. I also tried to recompile arts with the link pointing to /opt/qt4, but the ./configure failed when looking for Qt; (missing headers error), not sure what that means?

I've just done another restart and still have the same error.

This is the exact error message I am getting.

Sound server informational message:
Error while initializing the sound driver:

The sound server will continue, using the null output device.

What version of Qt4 are you running? where did you get your package/source? (I'll try the same version as maybe mine is broken?).

Thanks, I'll look forward to hearing from you.

Thats probably the problem. remove WengoPhone. IIRC , its not a dependancy for Qt4.

I have installed from source as well as package , either is fine . Compilation takes a looong time though.

Hi Guys,

Sound is back! Thanks very much!

It seems wengophone was the culprit, removed that and all good again.

Thanks again for your help

Cheers
