Raspbmc XBMC 12.2 Buzz with HD flac - MrNice - 2014-01-18

Hi,

I installed a new SD card with Raspbmc XBMC 12.2 GT 20131304 - 5a51fa8
I think this is the last stable version.
I only set-up clock, localisation, Speakers config, stopped the fidgeting background and adjusted the CEC to start/stop the AVR.

I found the following issue or bug:
- Test with these audio files
* 8_Channel_ID.wav from http://www-mmsp.ece.mcgill.ca/Documents/AudioFormats/WAVE/Samples.html
* ForUntoUsSurround88.flac from http://www.linnrecords.com/linn-downloads-testfiles.aspx
* Bjorn_Lynne-Voyager_(surround).ac3 from http://www.lynnemusic.com/surround.html
* www_lynnemusic_com_surround_test.ac3 from http://www.lynnemusic.com/surround.html

ForUntoUsSurround88.flac mediainfo:
Audio
Format : FLAC
Format/Info : Free Lossless Audio Codec
Bit rate mode : Variable
Bit rate : 5 837 Kbps
Channel count : 6 channels
Channel positions : Front: L C R, Back: L R, LFE
Sampling rate : 88.2 KHz
Bit depth : 24 bits
Writing library : libFLAC 1.1.4 (UTC 2007-02-13)

If I play first ac3 file Bjorn_Lynne-Voyager_(surround).ac3 or www_lynnemusic_com_surround_test.ac3 and after the file ForUntoUsSurround88.flac, I get one randomly channel with a loudly buzz, other channels playing.
If I play another type (not ac3) before the file, it is alway good.

I did a long test playing each files playing 5 seconds but only with the default player:
1 - Bjorn_Lynne-Voyager_(surround).ac3 then ForUntoUsSurround88.flac 20 times, I got 50% bad,
2 - www_lynnemusic_com_surround_test.ac3 then ForUntoUsSurround88.flac 20 times, I got 60% bad
3 - 8_Channel_ID.wav then ForUntoUsSurround88.flac 20 times, I got 0% bad, all good
4 - Repeat ForUntoUsSurround88.flac 10 times, I got 0% bad, all good

Could someone try the same files and tell me good or bad results?

Do you experience the same issue?
Thanks for you help, any questions and ideas are welcome
