Has anyone with chromecast gen 3 experienced audio stutter and skipping? 5 Recommended Answers 36 Replies 64 Upvotes

Since recently  (new firmware with rounded corners) I have noticed that youtube videos 1080p @ 60fps, have stuttering and skipping audio. 
Gen 3 chromecast is supposed to handle that format but obviously isn't up to it.  Unfortunately it will always default to 1080p 60fps if its available. This makes chromecast unusable for most of the newer content. I would be happy to watch youtube content in 720p without audio skipping but there is no way to select quality in youtube app. I tried to cap the bandwidth on my router (so that it would stay at 720p) and it only works if I cap it to 2Mbit/s, but that defeats the purpose (makes it slower that gen2). 
Oh and I tried absolutely everything (changing the TV, all the chromecast options, 5ghz router, cooling down the chromecast, absolutely everything).
So has anyone else noticed this? Is there any  possible solution?

Hello, thanks for taking the time to post your issue.
 
Does your phone, TV or router have a task killer app, standby, firewall, antivirus, sleep mode, power saver, a parental control, tv HDMI-CEC settings, wifi network extender, or electromagnetic devices (stereo receiver, DECT cordless phone, microwave, baby monitor, refrigerator, LCD monitor, etc) causing interference?  A wifi repeater may cause a micro second delay.
 
If you have DECT or baby monitor, or other bluetooth devices, make sure their batteries are fresh and check their user manuals about changing channels. Speaking of channels, if you have an Android device, install the Google Play app, Wifi Analyzer and run it. Your wifi router may be on a congested channel. Try channel 1, 6 or 11. Not Auto setting.  Please keep in mind that resetting or making changes to your router settings may have unintended consequences. If you have questions or concerns, please consult your router manufacturer or Internet Service Provider before making any changes.

Thank you for replying and your effort. Pretty much tried all the above and more. Including using different usb cable and power brick. Put a heat sink on chromecast even. Rebooting hard reseting. No use. We really need an option to choose streaming quality on chromecast from youtube. Im happy to choose 720p just to get smooth playback. I relly dont need 60 fps video. It worked great out of the box.  But with this new OTA firmware i got audio stutter and rounded corners on my tv. This is not what I bought 8 months ago.

Nope. You can only enable or disable preview firmware program, but that won't force an update, you'll only get an update once the next one is rolled out to you. Factory reset won't do it either, the installed firmware is retained.

Well, nice to see that it's a recognized firmware bug. 
One of the community specialists there has stated that  they will fix the rounded corners problem over the next update. Hopefully they will fix the 1080p60fps audio stutter problem also.

For the sake of keeping this relevant, issue is here as well. Super annoying when trying to listen to music. 
Firmware version 1.49.230269.

I've ruled out other causes like everyone else.

I hope this gets fixed soon, just got a Chromecast V3 (new one isn't out yet here) and I'm starting to regret my purchase

I am glad I found this issue, came here from the rounded corner thread which I found in some news site.
This is extremely annoying and makes the Chromecast unusable for certain content.
It's a shame for Google QA, and a shame that Google does not act quickly.

I hope the rounded corner firmware fix will also fix this. I don't care about the corners, but the skipping is really, really bad.

Twitchtv :

1080p60 8000 bitrate > Stutters
720p60   8000 bitrate > No Stuttering
932p60   9000 bitrate > No Stuttering (bitrate peaking to 10k)
1080p50 9000 bitrate > No Stuttering
1080p48 8000 bitrate > No Stuttering

This makes no sense! How come 9000-10000bitrate Not Stuttering, but only 1080p60 8000 audio stutters?

Download random Twitchtv 1080p60 clips and stream it with VLC to Chromecast = mostly Stuttering
edit2: here is downloaded clip video that stutters the most, sound cuts so much   https://drive.google.com/file/d/1DTfa_-ug--K-3QuMAIqitabSCDj2w_qt/view?usp=sharing  

On any live stream (edit: 1080p60) > still image with sound = Way more stuttering, When screen is moving it is getting less stuttering.

I used https://r-1.ch/analyzer/ to get twitch channel statistics, bitrate, fps etc 

Anyways. Peace.

edit3: And yes, youtube 1080p60 videos > same stuttering issue. 720p60 no stuttering. Sometimes video plays normal, but only audio stutter.

I got a new Xiaomi Mi Box S 4K and i can see i am getting 94-95mbit with ethernet, 55-60+ with wifi5.0, 35-37 with wifi2.4, and there is not a single issue on it with chromecast or twitch app. Same for youtube.
I also bought ethernet dongle for Gen3 and my speeds tests inside chrome was also Good enough for 1080p60 and more. ( i used https://play.google.com/store/apps/details?id=com.speed.chromecast&hl=en_US to speedtests from inside chromecast)
I bought 1m hdmi extender cable to test the chromecast gen3 away from TV, and still the same. I put folio behind tv, between chromecast and tv still the same. I added Passive Coolers + FAN to test it as last chance, still the same. Have a great day you all.
