Yes well... I dont want to be working for nothing thats all. I mean I dont want to spend tons of time writing docs and then someone goes and makes the work I done go down the pan. So as is, Im doing PA page and the rest I dont touch anymore.

The log file seems to indicate a couple of thing, first that it's struggling to send AC3 and that there's some video sync issues.

For the movie Red 2, what does you AVR show? does it show AC3 at all? or does it show PCM?

First thing to try is rename your guisettings.xml file in your userdata to something like old-guisettings.xml (to keep it for backup purposes so you can easily switch back to it) then start XBMC and a new guisettings file will be created, this makes everything go back to default so enter your audio settings again leaving everything else at default then try playing something again.

My AVR just says CinemaDSP I think it is....I cant see where it would say AC3 or PCM on the screen when its playing...also I went to user data, and there was not a file the was labeled guisetting....so I couldnt try to fix it that way?

sorry to keep bothering you, is there something else I should try to try to get this to work? Last night, I even tried to downgrade the system to 11.0 which I use on my other media server, and I was having the exact same error, it would just stutter the audio as I watched, however if I hit esc and went into the something else with the movie playing in the background it would not stutter at all, but play fully the way its supposed to. Also on my AVR, I have a 7.2 speaker system going, and it shows the speakers on the AVR, and as it stutters on the screen, it does on the AVR as well, like the area showing all the speakers will flash off and on as the sound goes on and off on the movie

Hello all,

I just found this thread and it looked like the right place to bring my issue. Similar to others I'm having no luck getting HD audio passthrough to work with Gotham where it worked well in 12. I've tried several nightly builds (the latest being 1/22.)

Essentially if I use WASAPI I can play the audio fine without stutters but my Denon AV receiver is not receiving passthrough it is receiving standard multi-channel. This is regardless of the format chosen.

I'm not sure if I'm missing something in 13 but I no longer see options for enabling formats and I also can no longer chose Direct or WASAPI independently. I'm assuming this is by design.

In any case moving from 12 to 13 and HD Audio no longer works. Nothing has changed outside of XBMC and if the requirements have changed there's no obvious indication that it's needed.

Thanks

Change your Settings Level to Advanced and you'll see the passthrough options.

In the settings GUI, there are now several modes (Basic, Advanced and Expert) - bottom left corner, which give access to varying degrees of settings, the ones you want will only become available when 'Expert' chosen.

Ah hah! Thanks I'll check that. Thanks!

I was looking for some help in getting my Dell Studio 140G to playback videos over my wired network the PC is connected directly to the TV via HDMI cable. I am hosting all of the files on a Synology NAS. XBMC v11.0 seems to have no problem with playback of the files. However XBMC v12.3 takes about a minute to load .iso files and a 720P .mkv files which leads me to believe there is something int the audio of video settings that is causing an issue.

Once the file loads it seems to play fine, but I am unsure why it needs a minute or longer to load when the previous version does not require this.

Dear OP! This thread (especially step 7, the PCM volume glitch) made my day, now i have the video playback problems solved. Thank you very much!

Hello guys,

I've a such a similar problem on my system. My HTPC is windows-based with XBMC 12.3, a Yamaha RX-V 671 and a Panasonic TX-P50VT30E.
With AVR turned on everything is alright.
With AVR switched off (Standby-Through), my videos with DD/DTS are stuttering. In the windows driver HDMI Output I see only 2 channels and stereo.

BUT
My TV can handle DD/DTS Audio Input. With my PS3 or XBOX360 I can play such signals.
Yesterday I tried also a raspberry with xbmc on my AVR. Here it is working without a problem in the Standby-Through-Mode.

Is there any chance, that I get the windows system working in that mode?

Thanks,
Shadow128

If you can do 2 debugs logs for me to look at, one with AVR turned on and one with AVR turned then I might be able to see what's going on and maybe offer a solution.

I think it's unlikely that your TV supports receiving DTS via it's HDMI input as I know of no TV that does this, but you never know and the debug log will show what the HDMI connection to the TV supports with AVR off.

Sorry I don't know what is going on here, I see nothing to suggest that audio is causing a problem.

Shadow128 · 2014-02-11, 13:13

OK, at home I'll do debug logs with the windows-htpc (avr on/off) and also with the raspberry (avr on/off).

What also surprised me: In the avr i can configure the hdmi setting. If the sound will be give out with the avr or the tv. While i choose "tv only", this also works.

**jjd-uk** · 2014-02-11, 13:30

Selecting TV only will likely break the ability of the AVR to decode passthrough formats, meaning it's then up to the TV to then decode the audio.

Shadow128 · 2014-02-11, 18:28

OK, i created some logs on my windows and raspberry / avr on and off.
Hope we can find the "failure"?

Windows HTPC - AVR on
Windows HTPC - AVR off
Raspberry - AVR on
Raspberry - AVR off

The issue is as I thought, the TV does not support decoding of Dolby Digital & DTS.

Line 34 of 1st log Windows HTPC - AVR on shows all the formats the AVR supports as expected.

Line 34 of 2nd log Windows HTPC - AVR off shows only 2 channel PCM support and none of the encoded formats.

There is no ideal solution for this currently, as it's impossible to have a single group of settings that covers both use cases AVR on and AVR off, when the terminating device (AVR or TV) has completely different decoding capabilities.

With the Frodo 12.3 build you have you'd need to configure 2 profiles for each use case as each profile can have it's own settings, and then switch between them depending on whether the AVR is on or off.

With Gotham 13 nightly build there is now a Default device setting available which may help in these situations, but even if that were to help there would be the need to restart XBMC to pick up the changed properties if for example turning AVR off with XBMC open.

The RPi uses a specially developed player, so this may account for the difference. I don't really know the RPi too well or how to interpret it's logs, but it seems to me in the 1st one with AVR on it passes 8 channel DTS to AVR and in the second with AVR off it downmixes to 2 channel PCM. So if it does this with no intervention from you it must be doing something clever that is not currently available on any of the other platforms.
