No sound in RealPlayer 11.

[popatopalous]

I admit I'm baffled. In Fedora 8 AMD 64 using KDE I have sound except [as far as I know] in RealPlayer 11. In RealPlayer 11 you can select whether it uses alsa or oss for audio. alsa is selected currently. In Firefox I have RealPlayer plugins enabled when I go to:

RTÉ Radio

BBC - Radio Homepage |

RealPlayer opens and plays but with no sound. I do have sound in Flash [You Tube] and mplayer [Apple Movie Trailers] as well as in kde.

Here's some info I gathered while searching forums:

If I select to play streaming audio at bbc.com and run:

# lsof | grep dsp
npviewer. 7485       ben  mem       REG                8,7    11124    2784367 /usr/lib/libartsdsp.so.0.0.0

I don't know what this means though?

Some more:

system-config-soundcard

does not play guitar chords in KDE but does in Gnome. Test Sound in KCC>Sound System>General does play sound though. Not sure if this means anything?

# alsamixer

opens mixer with ONLY Master Volume control. It lists:

Card: PulseAudio
Chip: PulseAudio
View: [Playback] Capture All
Item: Master

Master is, of course, unmuted and set to 71.

How can I troubleshoot/fix this? I would like to first figure out if this is a Fedora, or alsa, or pulseaudio, or kde problem? Or is it a RealPlayer problem? FWIW I DO have RealPlayer working [with sound!] on my other 4 distros. Also, by all means, let me know of any other info or tests that would help solve this.

Here's terminal output when I try to play something:

$ realplay

(realplay.bin:3525): Gtk-WARNING **: Unable to locate theme engine in module_path: "nodoka",
ALSA lib pcm.c:2106:(snd_pcm_open_conf) Cannot open shared library /usr/lib/alsa-lib/libasound_module_pcm_pulse.so

...

Obviously I don't have '/usr/lib/alsa-lib/libasound_module_pcm_pulse.so' how do I get it and get it to work? So what do I need to fix it?

And there's more. I downloaded some music videos with Azureus. If I try to open them with RealPlayer 11 they won't open because I don't have 'asx'. If I open them in Kaffeine it promptly crashes. If I open them in MPlayer they open and play with sound but there is an error message:

Error!
[AO_ALSA] Unable to find simple control 'PCM', 0.

I'm not sure how to fix your problem, but it looks like an issue with pulseaudio. for some reason libasound_module_pcm_pulse.so cannot be found. Run

yum whatprovides libasound_module_pcm_pulse.so

Reinstall the package that yum lists and see if that helps.

Thanks, that in combination with something I got from Fedora forum led to:

# yum whatprovides libasound_module_pcm_pulse.so
No Matches found
# rpm -ivh http://fedora.tu-chemnitz.de/pub/linux/fedora/linux/updates/8/i386/alsa-plugins-pulseaudio-1.0.15-3.fc8.1.i386.rpm
# yum whatprovides libasound_module_pcm_pulse.so
alsa-plugins-pulseaudio.i386 : Alsa to PulseAudio backend

So now I have 'libasound_module_pcm_pulse.so' and when I try to play something in RealPlayer... It crashes:

$ realplay

(realplay.bin:3473): Gtk-WARNING **: Unable to locate theme engine in module_path: "nodoka",
Opening ALSA PCM device default
realplay.bin: pcm_params.c:2351: sndrv_pcm_hw_params: Assertion `err >= 0' failed.
/usr/bin/realplay: line 54:  3473 Aborted                 $HELIX_LIBS/realplay.bin "$@"

Wonder how I can fix that?

Edit: At least I'm learning more about Fedora and Yum. That's a good thing.

FWIW solution is described here:
