Stuttering audio, Roku Ultra HD 4k

I have a brand new (actually 2 brand new) Ultra that is intermittently having the choppy/stuttering sound issues.  The first model was ~2 months old and was doing it, and I had to end up replacing it through Amazon bc it would not pair with the remote after Roku support walking me through every possible option.  The new one has been installed prob 2 wks, and it is now stuttering - but the remote pairs and works fine.

I'm with other posters that Roku has some combo of software/firmware/hardware issues they need to work out.  I work in the high tech space and we mfr swr + hardware and I know how complex this is but you have to figure it out.  I hate Apple in general, and their older gen AppleTV device and remote, which I have three of and replaced with Rokus.  But Apple has never ever had the number of odd issues I've had with Roku devices.

@tummyrope 

Thanks for the inquiry.

Can you please provide more information about the issue you are experiencing? Is this issue occurring on a specific channel or does it happen on all channels? What OS is your Roku device running (this can be found in Settings > System > About).

With more information we will be able to assist you further.


Thanks,
Danny

I'm having the exact same issue. On every channel. Even the beep of selecting something in a menu sounds broken. It is definitely a Roku issue. Restarting the device works for a while.

Re: Stuttering audio, Roku Ultra HD 4k

Just the thread I was hoping to find...

I've been having the same problem on my Roku Streaming Stick (3800X)... all of a sudden choppy/jittery/stuttering audio on all channels. It happens sporadically. It's not even a new Ultra.

Would be nice to have a fix, I get tired of restarting the Roku, which is the only thing that fixes it.

Re: Stuttering audio, Roku Ultra HD 4k

4800x OS 9.4.1, streaming from Nas to Roku media player.. All audio is choppy. I have an older 4640r that had OS 9.3 working perfectly with the same content. The older 4640r updated itself to 9.4 and now audio is broken on the 4640 as well. 

I returned the 4800 to Bestbuy initially and got a new one.. But 9.4 comes pre-installed on it. It's also going back.. But I stuck with a broken 4640 now.

Since then I got a nvidia shield pro 2019..and no issues. The old 4640 will either become a nice paperweight.. Or get torched. It's a pitty becuase I loved my Roku's.  Time to move on.

Re: Stuttering audio, Roku Ultra HD 4k

My Roku 4670X Ultra just started developing this same issue 3 days ago.  Software version is 9.4.0 build 4200-46.  System restore fixes it for about a half hour and then problem returns. Stutters about every 2 seconds.  Any fixes yet for this?

Thanks!

Re: Stuttering audio, Roku Ultra HD 4k

I'm also having the same issue. Audio drop-out every few seconds while playing a 4k movie from a external SSD. 

Are there any suggestions for a fix?

Otherwise I'm dropping Roku and getting something else!

Re: Stuttering audio, Roku Ultra HD 4k

I did finally fix the issue! My setup is: Ethernet (or Wifi) signal with content feeds the Roku, then the Roku acts as a source, feeding an Anthem 1120 receiver. Both the Roku and the Anthem have the ability to decode Dolby Atmos signals.  When I disabled the Roku decoding of the Atmos signal (set it to audio pass-through mode) the problem went away. The Roku needs to be in pass-through mode, so the un-decoded audio signal makes it to the Anthem. Then, the Anthem can decode and replay the audio signal as it is designed to do.

I hope this helps you. Perhaps you have a Roku feeding a stereo or TV that also decodes Atmos signals. Just make sure the Roku is set to "pass through" (I can't remember the exact setting but it is under the Settings/Setup and Audio... you'll find it). And then the other device (TV or whatever) can decode the signal properly.

Now I'm enjoying the Roku Ultra - it's great.

Re: Stuttering audio, Roku Ultra HD 4k

Thanks, but I'm unable to see a "pass-through" option. I only see PCM-Stereo, and other audio formats available as options.
