Description Wallace Lai 2007-10-16 09:10:16 UTC

System Info:  System Independent.  Tried on 3 different systems -- Win 2K SP4 ENU, Xp SP2 ENU, and Vista Gold ENU

Note:  Found on 3 Windows.  Has been manually confirmed on Win 2K SP4 ENU.

Steps to Reproduce:
1.  Put two identical mp3 clips with 16 bits, 8000 sampling rate, and 440 Hz into the playlist.
2.  Play them.
3.  Notice when the SqueezeBox display drops to -1 second.  The sound is gone.  A gap appears.

Wallace, is this a bug that you just started testing, or is it a bug that just started happening?  Can you tell what date the bug started on?

This is almost certainly a firmware bug, since mp3 files are decoded in the firmware of the SB3.

Also, I am reducing the severity of this bug since very few people use this format.

Comment 4 Wallace Lai 2007-10-16 17:16:34 UTC

This has happened for several builds now.
What are the most popular formats of mp3?

Comment 5 Chris Owens 2007-10-16 17:39:30 UTC

44.1KHz 16bit Stereo is 95% of users (my estimate)
8Khz and 11KHz are pretty low down the list.  They have very low audio quality.

This is definitely a bug, since we claim to support this format and we claim to support gapless playback.  I'm just considering the other work Felix and Richard have to do.
