Windows 10 + MP1.12 Audio Renderer issues (2 Viewers)

[Sebastiii]

Hi

From analysis from buddy of mine/us :
04-08-2015 14:26:41.672 [ 1010] Unable to find selected audio device, using the default end point!
04-08-2015 14:26:41.674 [ 1010] Default audio endpoint: "Speakers (Intel SST Audio Device (WDM))" ({0.0.0.00000000}.{2cc7e9cc-38df-477b-bd11-5e6caa20b3cd}) - pull mode: 1 sprk mask: 0

It is worth to check if that is the audio device that is wanted to be used, W10 install probably reinstalled (or even changed) audio drivers which causes device GUID to change and if there was previously an selected device it is lost.

You can see it with Filter config :

Click on screw driver :

In audio device, you can select the os default like above or different one.

YES! Thankyou so much Sebastiii, that's exactly what it was! Well worth keeping this in mind for other users updating to win10.

Thanks again!

Sorry to resurrect this thread but I am having issues too since upgrading to Windows 10.

When it first RTM'd back in July, I initially upgraded, but then had problems using surround sound - a long read through this thread here appeared to suggest that there was a known bug in Windows 10: http://answers.microsoft.com/en-us/...diosound/f1bf8029-e6f0-4eaf-9645-d041dbdf8b5b

A fix was apparently included in the last Fast Ring build which should have made it into the latest November/TH2 update released last week so I decided to try an in place upgrade again.

Unfortunately though, I am still having an intermittent issue using MPAR and sometimes it works, sometimes it doesn't - does anyone have any ideas/suggestions?

I have attached the logs - the first two videos I tried playing played with no sound at all, but then I tried a film and it worked fine and then proceeded to close MediaPortal. It seems hit and miss as to whether things will actually play or not. Windows 8.1 works absolutely flawlessly so I am not sure whether this is the above "bug" that is still causing these issues.

Many Thanks.

Hi Adam86

Thanks for reporting. Unfortunately the log files you've provided are of limited use. The biggest problem is that verbosity was set to "information" so we don't have full debug output. I assume that's because you used the Watchdog with option 3 (instead of option 2 or option 1 which would have been preferable).

I can see that you play:

• \\LOUNGE-EDGEHILL\TV-Series\The Job Lot\the.job.lot.s03e03.720p.hdtv.x264-tla.mkv
• TV channel "BBC Three HD"
• \\LOUNGE-EDGEHILL\MediaPortal\Movies\Transformers- Dark Of The Moon (2011)\Transformers- Dark Of The Moon (2011).mkv

For "The Job Lot"...
The MPAR logs only cover the two most recent streams, so I have no way to see what went wrong with this video.

For "BBC Three HD"...
MPAR has known limitations/issues. There's no guarantee it will work with TV streams. As it says in the wiki:
http://wiki.team-mediaportal.com/1_...nfiguration/9_Codecs_and_Renderer/1_TV_Codecs

MediaPortal Audio Renderer is often recommended for smooth video playback. However, it may not work with your TV provider(s). If you have TV playback problems (pauses, unsynchronised video/audio, no audio at all) when using the MediaPortal Audio Renderer, try another option (eg. DirectSound).

In other words, I'm not particularly surprised that you had no audio here. The recommendation is to use a DirectSound audio renderer for TV.

For "Transformers - Dark of the Moon"...
No problems, so no comment required.

If you would like further assistance, please collect and attach fresh log files using the Watchdog with option 2 or 1 so that we get full debug information. Please also restrict your testing to two videos/streams so that we will be able to check the corresponding MPAR log files.

Regards,
mm

Morning mm1352000,

Really sorry about the log level verbosity. I've changed that now and ran the same clips again and reattached the logs just incase anything can be identifed.

Understand where you are coming from about issues with TV Playback being documented in the Wiki, but when I was running Windows 8.1, I had zero issues with MPAR on the TV Side of MediaPortal. My Brother and Dad run the same setup too and theirs has always been flawless. Neither of them have upgraded till Windows 10 until they know that my setup is working OK, so I am unsure whether they would have the same issues as me.

Any advise would be greatly appreciated.
Thanks

Good morning

Thanks for the fresh log files. I'll try to take a look at the TV stream (BBC One HD). Once again though, I'm not able to look at "The Job Lot" due to the limits on how much logging the MPAR keeps - the logging is strictly limited to the 2 most recent streams. So, I have MPAR log files for BBC One HD and Transformers, but nothing before that.

[edit: Oh, forgot to ask: can you please also attach screenshots of the LAV audio codec settings that you're using. The first 2 tabs (audio settings and mixing) are the ones I'm interested in.]

[edit 2: ...and a screenshot of your MPAR settings, just to double check them.]

 

[Adam86]

Just incase it helps I have just exported the logs again by only playing "The Job Lot"

Also here are the screenshots requested - Thanks

Yeah, that definitely helps - thanks.

I'd like to preface the comments below by emphasizing that I'm not an MPAR expert. The primary reason I responded was simply to ask for the information I knew would be needed to help you. Now that the information is available, I'm hoping somebody who is more knowledgeable will be able to step in and assist. Until then, I'll try to help as best as I can...

To me the logical thing to do when approaching this problem seems to be to compare the MPAR log files for "The Job Lot" and "Transformers" and see if any differences stand out. My assumption in doing this is that any differences in the logging would somehow explain or correlate to the difference in playback results. So, that's what I've done. The only significant difference that stands out to me is the difference in source audio encoding.

• The Job Lot = 2 channel MPEG 1 layer 2
  
• Transformers = 6.1 channel DTS ES

Are you able to say whether there are similarities or patterns with results for other sources?
For example, do you always have failure with mono (1 channel) or stereo (2 channel) sources, and always have success with 5.1, 6.1 and 7.1 channel sources?

With regard to MPAR + TV...
I'm struggling to follow those log files due to the limitations of my knowledge/understanding. The only intelligent question I feel able to ask is: does it make a difference if you switch to the alternate/other audio stream? To be clear, BBC One HD has 2 audio streams:
[2015-11-18 06:46:27,263] [2a6f1940] [2a00] - audio pid: 40 language: NAR type: MPEG1 - audio
[2015-11-18 06:46:27,263] [2a6f1940] [2a00] - audio pid: 41 language: eng type: AC3

The log files show that MP selects the 5.1 channel AC3/DD stream. I'm wondering whether there's any difference in result if you try the MPEG 1 stream.

 

[Adam86]

I would say 90% of the time it fails to play any sound on anything that is only in stereo - surround sources appear to work each time flawlessly.

At a guess I would think the BBC One HD stream at that time would have only been AC3 2CH as it was only the news that was on. When I get home from work later I can try playing TV and switching to the Narrative Stream and seeing if it makes any difference.

Really appreciate you looking at the logs.

Interesting.

The log files show that MPAR downmixed the Transformers audio:

I wonder what would happen if you enabled the MPAR force up/down mixing option/setting.
