Hello,

I've recognized intermittently no audio after skipping actions (with courser keys). The 30 seconds or 10 minute predefined steps.

It is a ripped bluray stream which run very well in Kodi Helix 14.2.

The Audio Stream is AAC (LC) ([255][0][0][0] / 0X00FF) 48000Hz, Stereo, FLTP, 128kB/s

I'm able to get rid of the error with repeat pressing play/pause until sound is back, it works usually after 4-5 tries.

The first two lines of the error log are the issue, this line is spammed if I let it play with the error, in this excample I was able to get back sound at the end last 4 log lines:

Hello,

sorry for the missing log file, here it is:

Try it with the audio engine entries on advancedsettings.xml commented out also disable VAAPI in kodi settings if enabled and enable vdpau only for AMD

[fritsch]

Won't help.

<audio>
<resample>0</resample>
<audiophile>1</audiophile>
<audiosinkbufferdurationmsec>200</audiosinkbufferdurationmsec>
<allowtranscode44100>0</allowtranscode44100>
<streamsilence>1</streamsilence>
<dont_resample>1</dont_resample>
<audiophile>1</audiophile>
</audio>

Those are not existent anymore and would make no sense at all when using pulseaudio server

[kitsab]

Hello,

I've commented out the audio section in advancedsettings.xml, I disabled VAAPI and VDPAU (even I own AMD Proc an graphics). But the behaviour is still the same.

Code:

<!--  <audio>
      <resample>0</resample>
      <audiophile>1</audiophile>
      <audiosinkbufferdurationmsec>200</audiosinkbufferdurationmsec>
      <allowtranscode44100>0</allowtranscode44100>
      <streamsilence>1</streamsilence>
      <dont_resample>1</dont_resample>
      <audiophile>1</audiophile>
  </audio> -->

Thanks for further suggstions.

Get me: glxinfo | pastebinit and vdpauinfo | pastebinit please

From the log I see heavy audio dropping, cause your CPU alone is too slow to playback that file, even multithreading is used.

[kitsab]

Hello,

I've captured glxinfo ( http://pastebin.com/Wv0bvbHD ) and vdpauinfo ( http://pastebin.com/H1b10tam ) now, also I used top to monitor processes and CPU load.

The CPU load with no sound is around 98%, but as it is a dual core I thought each CPU is capable of 100% load for my system which has a dual core cpu it should be 200% max?

In Kodi 14.2 when I was playing bluray discs the load is up to 140% and all worked fine. No sound drops no video dropouts.

Thanks and best regards

Jep, post another Debug Log please - I want to see the threading again.

[un1versal]

VDPAU is OK enabled, VAAPI is not your GPU will use VDPAU with OSS AMD drivers.

[kitsab]

Hello,

thank you for investigation:

Debug log: http://pastebin.com/x80QjnL2

CPU load for kodi process in debug mode ~89%

Best regards

[un1versal]

I gave up reading that log after scrolling for 20 minutes. still seeing white spots.

[fritsch]

VDPAU neither - see the vdpauinfo output. It's RS870 which does not support h264.

The rest is fine:

18:45:02 T:139653220775680 DEBUG: CDVDVideoCodecFFmpeg - open frame threaded with 2 threads

All threads used.

Btw. please change your audio device away from the "combined" sink to a single output sink - any changes?

[kitsab]

Hello,

ok I now tried it with only HDMI audio output active, and you're right the issue doesn't show up with single output.

Has something changed from Helix to Isengard that could cause this issue I'm using dual output since V11 Eden with the same hardware and it always worked for me?

From the OS side nothing has changed since Helix upgrade to Isengard.

The CPU load is not influenced by this setting but the sound skipping disappears in the log with only one output active.

I'm missing this possibility even if I have switched it of 5 minutes ago. I ran the digital audio to my TV and my Amplifier, some thing I'm watching only with TV active but a few films and concerts I like to watch with my amplifier.

I hope this will be fixed, or could there be another way to get around the sound skipping with simultan sound output active.

Thank you so far for finding the reason!

Best regards

Kitsab

There are some pending fixes for ffw / rewind and flushing decoder, those will land in 15.1 - see the testing thread.
