Movie will not play with audio passthrough enabled

[DADAMAJA 3]

Hi

I recently started using Emby Theatre rather than MPC-HD.  I have my media box hooked to my AVR (HK AVR354) via HDMI (Radeon HD6450) and have never had an issue with pass through while using MPC.  When I enable passthrough in Emby Theatre, the loading circle spins then stops and the movie never starts.  If I disable passthrough, then all works as it should.  The AVR shows Multi-CH PCM which is ok but I would rather the decoding to occur on the AVR.  I am on version 3.0.19.

That log won't help. You'll need the mpv log. But before we get into that, let's try some trouble shooting. First try each codec option independently. AC3 first etc. What are the results?

[DADAMAJA 3]

If I select AC3 and play something with an AC3 codec, then it hangs.  In doing more searching and troubleshooting, I was able to seek forward or select the first chapter and it would proceed to play.  In searching, it seems to be related to spdif being checked first and since I am using HDMI, it fails.  I tried to add a mpv.conf with logging enabled but was never able to get a file generated.

Can you post the contents of your mpv.conf?

[DADAMAJA 3]

I used Glow to create the conf file and was able to generate a log.  I generated the log using a remote session so I see that it attempted to load "Remote Audio" but it seems to fail the same as if I was on the box.  I also noticed that it attempted to use spdif which I am not using.  I thought I saw a thread where this would cause issues like this but cannot seem to find it.

mpv.conf mpv.log

[generiq 113]

Ok, most of your conf is useless and possibly problematic, unless you are using mpv directly. Later, I'll re-write it, troubleshoot and give further advice. But for now, comment out the hwdec line, and all of the audio. 

[DADAMAJA 3]

Thanks!!  I commented out the lines and so far same thing.  I'll wait for your update.

[generiq 113]

Post a log after reproducing the issue once. Not remotely. It needs to be local to your machine

From your log.

In your Theater settings, switch the video output to gpu-next.

 

I'm going to attach your modified mpv.conf. I've removed many entries. Some of which can be toggled in Theater. Enable them there if you want them. But just remember, enabling them doesn't necessarily mean they are operational. mpv will silently disable some things if not properly implemented. I've added a few lines. 

In Theater, select auto for hardware acceleration.  

If this doesn't fix it, try a clean installation of your gpu driver.

mpv.conf

[DADAMAJA 3]

Set to gpu-next, I only get the circle spinning and the movie never loads.  Setting to Auto at least allows me to select a chapter and play.  I did a fresh re-install of the drivers and same thing.

mpv.log

[generiq 113]

Void your mpv.conf and try again 

[DADAMAJA 3]

Without mpv.conf GPU-Next still does not load.  Set to auto and passthrough disabled, all works as it should.  Re-enable passthrough and I have to select a chapter for the movie to play.

With gpu-next enabled, does it generate a log?

[DADAMAJA 3]

It did not originally but I re-added a mpv.conf with only logging and reproduced the issue.  It only spins and never loads with GPU-Next.

That's the end of the log. There're no audio device entries. It's as though something is blocking the audio device and mpv stops/crashes.

I'm attaching a standalone mpv complete with conf. Unzip the folder to your desktop, double click mpv.exe, and drag a video on it. Does it play?

mpv.zip

[DADAMAJA 3]

Sorry for the delay.  I tried it with the attached MPV and it crashed immediately upon dragging the movie.

Same deal, no audio device or any audio. In the conf I wrote, comment out the the audio-spdif line, run it again and post the log please. You are testing locally, correct? Not remotely in any way?

[DADAMAJA 3]

Yes I am testing locally.  Commented out the line and same results.  

mpv.log

[generiq 113]

This is nuts! Ok, delete all entries in the conf except for logging. And try once again. The log ends before any audio is initiated. I need to see what devices it's detecting. My sense is that you've got something different with your audio device.

[DADAMAJA 3]

It really is!  So I did a series of test.  It seems that everything works with hwdec and audio-spdif commented out.  With audio-spdif uncommented, the video will load but will not start until I seek forward.  I disabled onboard audio at the bios a while ago so only audio device I have is HDMI.  It always sends multi-channel PCM to my receiver so the decoding is happening on the box rather than bit-streaming to the receiver (HK AVR354). My box would bitstream outside of MPV/Emby Theater (i.e. MPC) but with all of the troubleshooting it seems that I have changed my config.  Ideally, I would rather have everything working through Theater anyway so I am not too concerned.  If I could even have music use custom ffmpeg settings, that would be clutch but I doubt that would be possible.  Anyway, I have attached all of the logs and current mpv.conf

mpv_allaudio.log mpv_allout.log mpv_allvidexceptvo.log mpv_current.log mpv_hwdecout.log mpv_spdifoutnovid.log mpv.conf

[generiq 113]

Ok, I haven't checked the logs yet, but the one thing you said that stands out is disabling the audio in the BIOS. Windows behaves in strange ways. Try re-enabling it. If that works, we can easily specify which audio device to use, in the conf. As for music, yeah, we can probably write an auto-profile for that. I used to do that for myself.

[generiq 113]

Ok, now I can see your audio device. I'm almost certain this is happening because you disabled the audio in the BIOS. If I'm correct, it disables the driver needed to allow mpv to pass the audio. So if you want to ensure that Theater/mpv only uses a specific device, we can add that to the conf.

[DADAMAJA 3]

BINGO!  Enabled onboard audio in the bios, and added audio-device=wasapi/{53e410fa-44d1-48bd-8c4b-6961def6ab32} and everything worked in MPV including bitstreaming DTS-MA and TrueHD.  So I dropped the MPV directory in appdata/roaming, re-configured audio passthrough and set video output to auto and all worked as it should in my limited testing.  As for the auto-profile, where and how would I create one?  I have a pretty simple ffmpeg setup so i would not think that it would be too involved.  Huge thank you for all of your help.

I have been doing some reading and I have an idea of what I would need to do.  I am assuming I would start with something like:

##Conditional Auto Profiles##
[profile_for_music_files]
profile-desc="profile for music files"
profile-cond=(filename:match"%.mp3$" or filename:match"%.flac$") ~= nil
af=

I exported the config from FFDShow and the filters I want are:

volNormalizeMax=400
eq5=79
isEQ=1
orderEQ=2
eq0=95
eq1=69
eq0freq=3125
eq5freq=100000
eq8freq=800000
eq9freq=1600000
eqSuper=1
showEQ=1
eq2=79
eq3=84
eq4=80
eq6=77
eq7=92
eq8=107
eq9=116
eqLowdb=-1200
eqHighdb=1200
eq1freq=6250
eq2freq=12500
eq3freq=25000
eq4freq=50000
eq6freq=200000
eq7freq=400000
mixerExpandStereo2=1
mixerVoiceControl2=1
mixerClev=117
mixerSlev=110
mixerLFElev=100

Would I add the above filters in AF= or is there a way to cross reference the correct filter names I would use?
