Bug Description

Binary package hint: lastfm

Bug occurs when trying to start playback of a station. This is since I'm on Hardy alpha I think, but I do recall the player working on Hardy once, just not sure.. no trouble with things like rhythmbox/flash/totem sound. The sound server selected for "Music and Movies" in Gnome's sound settings does not matter, although I need to try Alsa later since it reports the device's being used by another application (no idea which).

Command line output if generic audio device is selected in lastfm player's radio settings (soundsystem settings also only show the Alsa system):

ALSA lib pcm_dmix.c:866:(snd_pcm_dmix_open) unable to open slave
Floating point exception (core dumped)

Command line output if Nvidia card is selected:
Floating point exception (core dumped)

(no errors from ALSA)

cat /proc/asound/cards output:
0 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xfe024000 irq 16

Hi. I can confirm this. I'm able to crash lastfm if something else is
already using the sound card.

The attached patch works for me. Would you mind trying it? You just
need to put it in the patch series after alsa-qdebug.diff.

If all goes well, I'll notify upstream.

To get your fix included in Ubuntu, try transforming it into a debdiff (http://wiki.ubuntu.com/PackagingGuide/Recipes/Debdiff) and submitting it for review (http://wiki.ubuntu.com/SponsorshipProcess).

I'll soon upload a fixed version to Debian and ping the bug report once
it makes it in the archive.

lastfm 1:1.4.2.58240.dfsg-1 is now in Debian unstable. It should no longer
crash. The client will instead pop up a warning and refuse to play if it
cannot open the audio device. This, I think, was the intended behavior.

Changelog:
lastfm (1:1.4.2.58240.dfsg-1) unstable; urgency=low
  * New Upstream.
  * Build with libgpod-nogtk-dev.
  * Added patches:
    - check-soundcard-errors: Don't crash if another program is already using
      the audio device. See LP #188490 for the original report.
