SMPlayer Support Forum

I'm having problems getting SMPlayer to pass through options to MPV successfully. When I run MPV directly via command line with "mpv --audio-device='alsa/hdmi:CARD=NVidia,DEV=2' --audio-spdif=dts-hd,dts,ac3,eac3,truehd filename.mkv" DTS, DTS-HDMA, Dolby Digital and Dolby TrueHD all pass through to my receiver without issue. When using SMPlayer and I try to pass those parameters through to MPV via Preferences --> Advanced --> Options for mplayer/mpv --> Options I don't get any audio at all. FWIW, I've tried the parameters with both the "--" and "-" prefix but neither works What is the correct way to pass through those parameters? Thank you in advance for any assistance!

Cheers,
Pete

Can you send the mpv log?

Hello guys! I am new here and I will try to describe my problem. During 3 months i was trying to play 4K movies on my PC. I have a I7 - 4770K, 8GB RAM, and Nvidia Gefroce 1060. After I tried many players and can't play the 4K movies, I knew SmPlayer. This saved my life. With it, i watch all my 4K movies smoothly and with beautiful colors. But I am having an issue: All my movies that have sound DTS, DTS-HD Master or DTS:X work perfectly, my receiver passtrough perfectly, just enabling the option in the player "AC/DTS trasmiting under S/PDIF and HDMI. BUT, now my problem: the movies that have sound Dolvy Digital or Dolby True-HD don't work. The receiver do no recognize these sounds. Is there a solution? What do I have to do to put these sounds to work? I appreciatte your help and wonder if there's a solution.

Is there any error message in the mpv log when this happens?

How do I see this? Sorry, but I do not know nothing about this. If you tell me how to see the log, and what do I have to see, I do it for you.

rvm, i found it! I am very sad because now i am having problem with DTS too. I turn on my PC and play a DTS movie, and do not work at all. Yesterday, it was running perfecty. Look the logs:

It seems mpv can't find the audio device. Go to the menu Audio -> Send audio to, and check if it's using the correct one.

rmv, i have tried to do this. When I did this, all the DTS or DTS HD-MA worked fine. But with Dolby Digital or Dolby True-HD I did this too, but nothing change. I was looking on the logs and I noted two things between the log of the DTS-HD MA movie and the Dolby True-HD (in bold). Look:

This can be the problem?? Thank you again for your help.

Try this: go to preferences -> advanced -> mplayer/mpv, type this in the "options" field:

--audio-spdif=ac3,dts-hd,truehd

Let me know if this fixes the problem.
