Issue with periodic audio "skipping" - TheShoe - 2015-08-14

have the 15.1 release installed on OSX and the audio for flac (96/24, 192/24, 2.0 or 5.1 channel) sometimes seems to "skip" every few seconds where the skip is very brief (< 1s). almost as if the audio cuts out.

any suggestions on how to triage this?

audio is output over HDMI, 7.1 channel setup; running on latest mac mini, yosemite, 8 GB, hared-wired network conenction and media mounted over SMB from an ubuntu snapraid server

i haven't tested video yet to see if the issue manifests itself there as well. will try, but curious if anyone else has had this issue or similar.

TheShoe,

In your case, does the video sort of have to speed up then to try and compensate for the audio glitch?

I've noticed this a bit as well in recent builds, but chalked it up to bad rips...Now I'm starting to see it more.

Memphiz, if I can duplicate the problem reliably in a video I'll get a nice debug log for you with details on when the problem happened.

I haven't had an issue with video other than an audio synch issue where -250ms seems to do the trick (same as Plex interestingly). This is strictly with FLAC audio file playback.

Anyway - I haven't had a chance yet to get back to this. I intend to, but have been busy with other things...

finally got the debug log file:

debug log

this was playing a 7 min track of a 5.1 48Khz flac audio file

note this does not happen every time.

i'm also streaming the audio from an ubuntu server with the drive mounted over SMB.

i checked read/write speed which is 109 MB/s which should be plenty fast for this.

ok - sometimes the obvious is missed - advancedsettings.xml was not loading; seems it was in rtf format, not plain text.

fixed that and now re-testing with my buffer settings... if not resolved i'll regen a new Debug Log and post

RE: Issue with periodic audio "skipping" - TheShoe - 2015-08-30

RESOLVED

pilot error - my advancedsettings.xml file was not loading because it was RTF and not TXT format. duh!

...and thus the network/buffer settings I set were not being applied.

so far 30 mins of various mixed format flacs and not a single problem. never been able to do that long without issues

last post on this:

the problem is definitely resolved. hours of listening to various FLAC files of multiple channels, but depths, and sample rates, and not a single issue. here are my settings for the curious:

Code:
<advancedsettings>

    <network>

        <cachemembuffersize>157286400</cachemembuffersize>

        <buffermode>1</buffermode>

        <readbufferfactor>20</readbufferfactor>

    </network>

</advancedsettings>
