@zenithangunn @kampfkarnickel @twm7

I set up one of my old RPi1 Model B, 512 with a newly flashed Class 10 Sandisk Extreme SD Card using a 2A power supply, ethernet connected. Overclock settings as follows:

 arm_freq=900
 core_freq=450
 sdram_freq=450
 over_voltage=6

After setting up my Preferences for Audio (same as suggested above), logging in to MyPlex, I played a 320 kbit/s .mp3 album and a 256 kbit/s .m4a album with no problems. I can’t reproduce what you are getting.

As @Kwiboo stated above a sample file would be useful.

Thanks for looking into it, Here’s an example file and a favorite of mine.

I double checked my overclock settings (pretty sure I tweaked these a bit back), they are set to this currently:-
RasPlex:~ # vcgencmd get_config int| egrep “volt|freq”
arm_freq=950
core_freq=450
over_voltage=6
sdram_freq=450
RasPlex:~ #
And the skipping has stopped after I rebooted. I’ll monitor for a few days and let you know if its working.

Hopefully thats it, unfortunately I don’t have what I had the settings set to before.
Thanks guys, anyone still with this issue, run the above command and check your overclock settings.

@zenithangunn Thanks for the sample file, I was able to reproduce the skipping using that file and a RPi1-B+.

Just FYI I still see skips (CSoftAEStream::GetFrame - Underrun), but they are sometime less frequent. Sometimes more.

It seems random as too how much it skips (ie not related to the bitrate of the MP3).
I’ll continue to test, any pointers of where to look are always appreciated.

This issue requires a code fix and should work in next release (also fixes wma lossless playback).

Thanks for finding the problem!

Just FYI I am also having this issue. I happen to have a new RPi 2 as well as the older version. 0.7.1 works well on that with no skipping.

Wonderful. Can you share what the fix is? even a link to the commit would be great as then I can learn something new from looking at the changes
