Hi,
Since upgrading from KDE3.5 to KDE4.x I've not been able to hear sound through mplayer.

I'm running FBSD 7.1-p3
KDE4.2.0

Code: 
more /boot/loader.conf

accf_http_load="YES"

Have I built KDE4.2 correctly? What sound system does it use, arts? Have I built required ports correctly, phonon, libxine?

any advice much appreciated.
 
I found that building phonon with pulseaudio made my system very unstable and unable to hear sound. After I rebuilt phonon and switched to OSS as backend, no more problems.
 
no sound

I took a look at phonon to see if there is a knob to configure at build.

Code: 
 9# cd ../../multimedia/phonon
[/usr/ports/multimedia/phonon]
 10# make config
===> No options to configure
Leaves me unsure if phonon was built with or without pulseaudio.

Anyway, I installed oss. During the installation it correctly detected the CMI8738 audio. I edited /etc/rc.conf to enable. And I started the daemon.

Couldn't quite tell if it is really running. There's no pid file i could easily see in /var/run.

Code: 
 13# /usr/local/etc/rc.d/oss status
/usr/local/etc/rc.d/oss: unknown directive 'status'.
Usage: /usr/local/etc/rc.d/oss [fast|force|one](start|stop|restart|rcvar)

I opened the KDE4 control center and manually assigned audio to Open Sound System, and checked the duplex option. Only thing that makes me think oss might be running is:

Code: 
17807  ??  S      0:00.69 /usr/local/bin/artsd -F 10 -S 4096 -a oss -d -s 60 -m artsmessage
But even that's not so convincing..

using mplayer with option -ao oss fails to produce sound. Using cat {filename} > /dev/dsp, or dsp0.0 gives nothing either. Searching on the net I found a site that suggested CMI8378 was supported by oss. So maybe theres some setting I missed ..

Also, I wonder why artsd is running on my box. Is it the sound server by default? should I focus my time on getting arts working?

I read on some site to build libxine with xcb supprt, but again there was not knob for it..

Code: 
OPTIONS=        ARTS "Enable aRts support" off \
                CACA "Enable libcaca support" off \
                ESOUND "Enable EsounD support" off \
                JACK "Enable JACK support" off \
                GNOMEVFS2 "Enable GnomeVFS2 support" off \
                PULSEAUDIO "Enable PulseAudio support" off \
                XVMC "Enable XvMC support" off \
                SMB "Enable SMB protocol support" off \
                AALIB "Enable aalib support" off \
                IMAGEMAGICK "Enable ImageMagick support" off \
                GTK2 "Enable gdkpixbuf support" off \
                WAVPACK "Enable WavPack support" on \
                FAAD "Enable external faad support" off
I didnt change the default options above when last building ports after upgrading to 7.1. There must be something I've not built correctly..
 
My bad, it's x11/kdebase4-runtime that has the pulseaudio option. With OSS I meant the plain OSS that is in the base system. Though installing the port doesn't hurt, the drivers work better for most people.

Duplex option is actually a bad idea. It will claim device exclusively, so no other sound daemon or program wanting to use /dev/dsp can touch it. Your problem is likely the running arts daemon. Arts has been killed in KDE-4, though it's still running for me as well, for KDE 3 applications.

If you have arts with duplex configured, that is likely your problem. Since there's no more control module for it, you may have to dig into ~/.kde and find where it's configured.
 
Sound, period?

I think this has less to do with KDE and more to do with hardware. I'm just not getting any sound at all, period. I sign on to a shell, no KDM.

FWIW the oss port didnt seem to recognize my card. Or rather it did, but couldnt find a mixer..

Mixer device 0 doesn't exist.
So I'm not sure artsd is the problem since it isn't running just after I sign on to shell. Any advice on checking if the hardware really is working much appreciated. Handbook only goes into so much detail.
 
[SOLVED] KDE 4.2 sound

the combination of:
* compiling sound & snd_cmi devices into kernel
* upgrading latest phonon with xine backend

have now produced sound - both in KDE and from the terminal. I removed directives from /boot/loader.conf.

However volume is very weak even with every mixer setting pegged to 100. Seriously low levels.
