I am having an odd problem. When I play a video (h.264, approx 4.7 gb for 1 hour video) I get spikes or peaks in the sound. It is random, not very often, but very distinct. Hard to explain what it sounds like, but is it like a distorted high pitch, very short duration. At first I thought it was in the video, but rewinding does not reproduce. Which make me believe it is random. When I play music through airplay, no issues whatsoever. Sound is configured to 2.0 channels.
Pi 2 with latest OSMC, file on NFS share on NAS (network throughput perfect)
HDMI through Marantz NR1605 receiver
Not sure which configuration details are relevant, so please ask me if you need to know specifics. I am at a complete loss, because I can’t figure out where it is coming from.
Always provide logs.
To get a better understanding of the problem you are experiencing we need more information from you. Please see http://osmc.tv/wiki/general/how-to-submit-a-useful-support-request/ for advice on how to help us.
Alright, I did some logging (Logfiles). I cleaned it up a bit, removed movietitles and series. Shouldn’t be an issue. Left the rest in place.
Pi 2 with latest OSMC (normale clock settings)
HDMI video & sound, through Marantz receiver
Sony KDL-47W805 tv
I played around with the advancedsettings.xml a long time ago, not sure if updating OSMC overwrites these changes. So could be something I did myself obviously.
During a movie or series, I can hear halts or spikes in the sound. When I play music through AirPlay directly (!) through my receiver, I have no issues. So it should be something between Pi and receiver. I saw some errors regarding Alsa, but I am not sure that is the problem.
Any help is much appreciated.
I just did a completely fresh install of the latest OSMC and configured it all from scratch again. And it all feels so much more sluggish. Couple of things I noticed:
- starting a video takes about 5-6 seconds, before it was virtually instant. Now the sound starts, you can see the menu and then it switches to the video, audio is noticebly syncing and then it resumes.
- posters in movies view are often unloaded. I never turn my Pi off, and before, even with 150 movies, the posters, fanart, screenshots were always instantly available. Something changed in the kodi library with Jarvis?
- responsiveness has gotten worse, even with 60 Hz (matched with tv) it feels sluggish and slow, never had that before.
- stopping a movie or episode takes again about 5-6 seconds and oddly enough leaves the subtitle lines of that scene on a black background during this period
When I look through the forum, I see a lot of recent posts about slow video, dropped frames, lost audio and slow performance. However, I am not sure if this is all related to each other.
Is there something odd in my logfiles that you can identify? I can upload new ones, from the fresh install, if you want.
Anybody? You asked for logs @CaNsA
Why is nobody responding to this? I did what you asked: provided logs. I am willing to try any settings, but you just completely ignore it.
Mainly because eight months have passed.
I replied to your other post though.
Let’s get this solved. We’re happy to work with you on this.
- Try play back locally. Does the issue persist?
- Can you send me a file to reproduce the problem?
- Can you confirm existence of the problem on Nov 2016 update, on a fresh install?
- Have you tried a Kodi Krypton build?
I read all posts, but only reply when I have some ideas on how to help users.
That is a little unfair… 8 months have passed because nobody replied
But, let’s give it another go!
- I did play locally, still getting the spikes in audio. But I will try again this week to make absolutely sure.
- I can send you a file. However, the problem cannot be easily reproduced. The spikes are not always at the exact same moment. I tried rewinding numerous times to record the phenomenon on my phone, and each time, the spike wasn’t there. It looks as it occurs randomly. I will try again by recording longer period and shorten the video as ‘evidence’
- Yes, I can confirm that the problem exists on Nov 2016 update, freshly installed. That is mainly why I bumped this post, because I gave it another try.
- No, I have not tried Kodi Krypton, will try this week.
I will share an update with my findings this week. Thanks for helping.
Need MediaInfo, logs and a list of attached devices as a minimum.
I did some testing last week and interestingly enough, it looks like the Krypton build doesn’t have the same issues as the ones between 2016-05.02 and the latest November update. Needless to say, I am pleased with the findings!
However, I will keep doing some testing. I want to switch back to the November 2016 build and watch a couple of movies this week to see if they are still occuring on that release. I haven’t changed anything in my setup, so I expect the spikes to be there. If they are, I think it is safe to assume that Krypton solves the issue. Although I don’t understand how and what could be the reason.
Will report back with some definitive findings.
Sam, I am happy to tell you that the spikes have not accured since I switched to Kodi Krypton.
I did test with the same files on the same setup - but with Jarvis instead of Krypton and the spikes where clearly there. Not sure what eventually solved my problem, but I am happy with the current performance.
I think it is pointless for now to look for the bug in Jarvis and if - god forbid - the spiked return in any of next versions of OSMC, I will let you know
For now, thanks for the support.
