Please put the command line.
Do you try to write a file in a mounted CD-ROM? The problem seems not related with eac3to but with your wine-linux. I think than ALSA lib is not from eac3to.

I have a DTS-MA 7.1 audio track from a bluray movie that I want to convert to AC3 5.1. Eac3to report that the DTS-MA 7.1 track has a strange setup.
With the down6 option, eac3to seems to create a correct 5.1 AC3 file. Is MeGUI also able to create a correct AC3 from this DTS-MA strange setup audio track ? (see image for config options used in MeGui) |

@heerschop
The MeGUI downmix 7.1 -> 5.1 works the same for standard or strange setup. No problem. Even the MeGUI downmix (or BeHappy) works better than eac3to or ffmpeg downmix because, thanks to AviSynth plugin AudioLimiter (only 32 bits), mix only the 4 surround channels of 7.1 to the 2 surround channels of 5.1 leaving the other channels untouched preserving the full volume. @MrVideo There are two reasons to recode: save space and compatibility with some players (not all suport DTS) If the source is lossless, like DTS MA is, the encode have only errors of the AC3 encoder like the 'core' DTS have also. The quality difference between the 'core' DTS 1509 Kb/s and the AC3 640 Kb/s can only be listen with expensive audio equipment and 'gold' ears.

If you disregard the slight difference in quality....
Rather than use the lossless 7.1 DTS-HD MA stream it's often easier to use the lossy 5.1 DTS core to create a 5.1 Dolby Digital encode

LWLibavAudioSource (or FFAudioSource) can decode DTS HD or TrueHD 7.1 lossless (even inside a container), you don't need decode it previously.
But of course you can do it with eac3to.

Yes, the domain www homecinema-hd com don't work.
I don't know where find µGUI, but I can't recommend use it. Also Clown BD link (forum slysoft com/showthread.php?t=25818) don't work. Replaced with https://www.videohelp.com/software/Clown-BD v0.81 (May 31, 2013)

Can anyone think of a reason why eac3to would process a 23.976 FPS video stream as a 27.730 FPS one? I think it is the reason why the DTS track in one of my MKVs is completely out of sync. I did not encounter the same error when I used MakeMKV instead.

eac3to don't change the fps of video streams unless you specify a new one. For instance:
eac3to INPUT 1: output.h264 -changeTo23.976 and only fix values like -changeTo23.976, 24.000, 25.000, ... are available. You never can change to 27.730 with eac3to. Put a MediaInfo of your source.

Yes, "process" was probably a poor choice of words. But this is what I noticed when I looked at the log for "Deep Rising":
