I have a GT520 and I have also audio dropouts.
However, I think there are fewer with the 304.43 driver.
In case I run XBMC in a smaller window there are no audio dropouts, at least during half an hour play.

Have you tried any of the samples from here? A good site to use so that folks can all be using the same sample tracks to compare results.

i was unfamiliar with it before now but it doesn't seem like it would help that much. most of the samples are less than a minute long and this particular problem doesn't always present itself in that amount of time. i suppose i should try nailing down if it happens at the exact same time on every file or at least at the same spot in the same file every time but with a lack of development on the AE linux side i don't really see the point of it right now. additionally all of my dts-hd/truehd tracks are demuxed straight from the bluray so whether the samples work correctly or not it doesn't really help the fact that my movies don't.

Have you considered setting your logging level to Debug in advancedsettings.xml (that way logging will occur in the background without the onscreen debug information) so when it occurs again you have a log file to post to help the devs?

ZBox ID80 (D2700 + GT520M)

Has anyone ran across the following:

I've told XBMC my receiver does not support DD/DTS/anything EXCEPT LPCM.
Everything works great, receiver is getting LPCM for everything.

One failure:

Simple AC3 is mixed incorrectly. I'm hearing the rear surround channel in the front speakers.

The log is here: http://pastebin.com/pZAuPCpT
The relevant bit IMO is here:
Code:

Unless I misunderstand, FL is indeed getting FL(1) and SL(0.7070.) etc which I can clearly hear as well.

On a more general note: is there a known bugs post so I don't have to read through 32189473129847 posts to see if my issue has come up somewhere?

It seems benkibbey 's last commit fixed my pulseaudio issue.
It is now back on.

Actually, I think I see a problem earlier in the chain:
Code:
02:25:49 T:140423519516416    INFO: ffmpeg[E5FFB700]:     Stream #0:1[0x80]: Audio: ac3, 48000 Hz, 5.1(side), s16, 448 kb/s

Note the "5.1(side)"

I've been looking around the ffmpeg forums what 'side' means, but I can't seem to find anything conclusive. On one hand just interpreting the word 'side' it might mean side speakers (as opposed to fronts or rears) but given that AC3 is max 6 channel it doesn't seem sensible to think this is true here.

Fact is that when bitstreaming the file, my receiver sends the 'rear channels' to the rear speakers

Perhaps AE is treating 'side' as a hint to send the sound inbetween fronts and rears, but in this case, I would say it is not the intended situation with this specific type of files.

I was getting audio drop outs with dtsma until i selected "sync audio to playback" option now no more dropouts... no idea why this helped.

do you mean "sync playback to display" with "a/v sync method" set to audio clock? if so i sadly already have that set.

I played around with the system today. Changed some settings
- In Video-Settings and Playback, I set Render method to "Basic shaders (ARB) and removed "Activate Teletext"
- System-Settings and Audio output I changed Play GUI sounds to "Never"

After this I logged out and logged in with the XBMC login instead of Ubuntu.

Then I played some media without any audio dropouts
Music Videos
- DTS HD MA 48 kHz, HD 720P
- Dolby True HD 48 kHz, HD 720P
- Dolby True HD 96 kHz, HD 720P
- Multichannel PCM 48 kHz, 720P
- DTS HD High Resolution, HD 720P
Film
- DTS-ES Mtrx, HD 720P
- Dolby Digital 5.1, SD
Recorded TV
- DTS 5.1 HD 720P

I suppose there is some kind of timing problem when I use the Ubuntu login and perhaps the other settings doesn't matter.

I'm having an issue where audio drops out completely after playing a stream. It doesn't happen with every stream, but it will happen at some point during any session where four or five files are opened, or after changing a few channels in PVR.

This is occuring using SPDIF for normal and pass through audio. Device is an AMD Intel HD Audio integrated chip. (NVIDIA GT430 is installed but is _not_ being used for audio)

I'm not positive when the regression was introduced, I've been hoping it would be fixed on its own for atleast a few weeks. Audio was working fine before AE, and has been working since AE was added.

Here is a debug log where it occured: http://pastebin.com/85n6uaLm

Steps Taken:
  1. Start XBMC
  2. Go to PVR
  3. Select Channel 22-1 (line 2310) (No errors occur, audio plays back fine)
  4. Switch to channel 22-1 (line 2304) (Audio fails. video playback stutters. Audio fails for all subsequent streams)


Ubuntu 12.04, running XBMC over lightdm with no pulse-audio.

ALPHA6 break AE.
ALPHA4 and ALPHA5 are working great (HD movies with DTS-HD MA and True-HD, HD music 192x24).
ALPHA6: after turn off and turn on AV receiver I have dropouts for any movies and for any music.

Re: problems in two posts above - can one of you try the following tag in advanced settings.xml:

Code:
<audio>
   <streamsilence>1</streamsilence>
</audio>

For details on what it does see my post here: http://forum.xbmc.org/showthread.php?tid...pid1036295

Let me know if enabling that tag solves the above issues.

If I have been able to help feel free to add to my reputation +/- below - thanks!

DDamon:

It sounds like streamsilence would fix the issue, but I am seeing this issue whether it is enabled or not. The log provided has streamsilence enabled.

@schmoko - thx for the feedback - will look for other causes
