Hi all,
I have some WavPack audio files (.wv) and I don't manage to play them using either Amarok (2.8.0) or Kaffeine (1.2.2).
With Kaffeine I get no sound at all, Amarok instead plays a very distorted version of the track.
I've tried with VLC, Dragon Player and MPlayer and they all work fine.
Kubuntu 14.04, HDA Intel 82801JI (internal) sound card, GStreamer 4.7.2.
Can you help me?
Thank you in advance for your time,
Ocirne

Do you have any additional scripts or Replay Gain activated in Amarok? That could cause some problems, but if it plays in Dragonplayer there is no reason it shouldn't play in Amarok.

Hi, thank you for your answer.
Sorry, I have mixed the programs' names: Dragon gives the same output as Amarok (terribly distorted and noisy).
I don't have any such thing activated in Amarok.
Thank you
Ocirne

try switching to the phonon vlc backend and restart KDE, guessing you're missing a gstreamer package possibly gstreamer-plugins-bad or maybe gstreamer-plugins-good, whichever provides libgstwavpack.so

Hi, thank you for your suggestion!
That did the trick for Dragon and Amarok, but in Kaffeine it's still total silence.

What exactly did the trick? Adding the missing codecs or changing the Phonon backend?

As for Kaffeine: apparently they don't use Phonon, else the same trick would have worked as well. Can't help with that, sorry.

Kaffeine use Xine for playback

these are the Xine packages I have installed, your distro may have diff names or require added xine packages:

libxine2-codecs-1.2.5-90.5.x86_64
libxine2-1.2.5-90.5.x86_64
libxine2-pulse-1.2.5-90.5.x86_64

some distros (Mageia, Rosa) seem to have an xine-wavpack package

note: I created a wv file and could not get Kaffeine to play it, this might help with Kubuntu http://ubuntuforums.org/showthread.php?t=1482558

Hi,
the solution for Amarock and Dragon was switching to VLC backend.

Unfortunately, with Kaffeine I'm still stuck. I've got the library called xineplug_wavpack.so (found within Mageia's package), and I have placed it inside the relevant directories.
Calling Kaffeine from command line I get (apart from several (demux_wv_send_chunk:223) lines):

Code: Select all

demux_wavpack: (xine_input_push_back_byte:86) xine_input_push_back_byte: unable to seek.
demux_wavpack: (open_wv_file:150) number of samples: 6923700
demux_wavpack: (open_wv_file:152) samplerate: 44100 Hz
demux_wavpack: (open_wv_file:155) bits_per_sample: 24
demux_wavpack: (open_wv_file:159) channels: 2
assert: audio_pulse_out.c:407: ao_pulse_open: Assertion `!"Should not be reached"' failed.

So it manages to analyze the file, and it even moves the time cursor. But no sound is heard.
Any tips?
Thanks

just copying Mageia's .so file may not be enough as the associated libraries may be different/incompatible

seems that the problem is related to the Xine libraries so you might:
- search/ask on their site, forum, mailing as to why wavpack not playing or installed by default in Linux
- try compiling xine from the source, searching the source I see wavpack headers so I don't know if there a compile switch that needs to be enabled or what, probably --with-wavpack per an Arch posting
- ask the Mageia packager (if you can find them) why there's a separate package and how to compile and install it
- ask the packager on your distro if they know

ps - ask your distro's Xine packager to enable wavpack (assuming it's just a compilation switch), probably post as a bug report for Xine
