Yes, both audio track sound corrupt in the original, and both are correct in the extracted version.

Hi pieterg and all,

The original file with the corrupt DTS sound is to large for upload (20GByte)
So I extracted a small piece ~50MByte form the original file.
I made this by using mkvmerge.

And now the sound of the small MKV is OK (strange !!)

Because it make no sense to upload a file with correct DTS sound, I just attached the mediaInfo of both files for your information:

Hi folks

I can also confirm these problems.
I have also some movies (MKV containing DTS) with coppupted sound since the driver update last weekend.
I make daily updates by:
opkg update && opkg upgrade
and today the problems still exist.

MediaInfo of these files reports:
Format: DTS
Channels: 7 channels
Bit rate: 755 KBps
Sampling rate 48 KHz

@Sjaaky: restarting Enigma doesn’t solve the problem, if the mpd output is disabled it keeps disabled.


Meanwhile I had tested a little bit more:
The mpd output is mute (sometimes, not always), if I switch between TV channels which toggles the audio output between AC3 and MPEG. Then the mpd output is off and only a reset helps. Sometimes also the mpeg audio of enigma is off, so TV channels which provide only mpeg (no AC3) have no more audio.
I assume that Enigma does not initialize the audio correctly when it switches between AC3 and mpeg2 .

@tr45h
I "mute" the TV by switching to a "dummy" TV channel. I configure in my favourite channel list a entry where no real TV channel exist. So the box replied with “tuning not possible”. The screen becomes dark and the audio mutes.
To have it more comfortable, I configured my mpd-client (MPaD on iPad) to send an http command (TV channel switch) to the WebIf of the box.
But the problem is:
When I stop mpd playing and zap between TV channel, sometimes (randomly) the mpd-sound output is switch off. Restarting mpd does not help. The only way to get mpd control over the audio output is to reboot the box.

The problem is (my assumption) that Enigma takes the control over the audio output and does not release it.

@MiLo
Is it possible to force the control over the audio output (when mpd start) and release it (when mpd stops)?
