Public bug reported:
Binary package hint: rhythmbox
Gutsy 64-bit, Rhythmbox 0.11.2.
Playing large MP3 audio-books (in this case a 10-hour file - 286.9 MB)
causes Rhythmbox to keep the CPU(s) under heavy load and drives
temperatures towards the high-end of their range. Expected normal
temperature is 52C but I'm seeing 64-69C as one or other core is being
driven hard constantly.
System Monitor Processes tab reports Rhythmbox is sleeping and using 32%
CPU. CPU history tab shows one CPU at 60%, the other around 8%.
Occasionally the load swaps cores (presumably as threads start/stop).
As soon as playback is paused both cores drop to 2% usage and the
temperature rapidly falls back to normal levels.
Playing 'general' audio tracks (3-8 minutes) there is no problem.
Using an alternative music player such as XMMS there is no problem.
** Affects: rhythmbox (Ubuntu)
Importance: Undecided
Status: New
** Summary changed:
- CPU 100% and High Temperatures playing large MP3s
+ CPU 60% and High Temperatures playing large MP3s
** Description changed:
