You may find that Google Chromecast audio and video is choppy. To fix this and stop the audio and video from being choppy, you can change the following:
❗ Note: In this authors opinion, the Chromecast is quite rubbish. I’ve bought both versions and found them to be equally bad. I’ve even got a specific wireless AP to send my Chromecast traffic down the line and still there are various issues. Many of the below options have a good chance to help you fix your choppy video / audio, but the best thing to do in my opinion is return the Chromecast to the shop.
Make sure you are using a 2.4GHz Wireless n router and adapter on your streaming device. This will transfer the audio and video more quickly and prevent it from being so choppyThe Chromecast 2 now supports 5Ghz
- If you can’t improve the speed of your wifi, reduce the quality (and therefore the file size of the audio / video being streamed to Chromecast). To do this, click the Google Cast icon in Google Chrome as if you were going to cast something and click Options. From here you can change the Tab casting quality (which also effects the audio and video quality of casting the desktop if you are doing that). If you are currently casting something, you can change the same settings using the cog icon in the same place. Dropping to lower video rates will send less data over wifi and will make the video play better and less choppy. This will also make the audio less choppy because there will be more bandwidth available for audio on the wifi
- Your video may be choppy because the Chromecast device is having to work to change the resolution to the resolution of your TV. Try lowering the resolution on the device you are casting from. Set it to the lowest resolution available that is the same aspect ratio as the TV’s aspect ratio. This will reduce the effort that Chromecast has to do in order to display the video on the TV. If the video doesn’t 100% fit on the TV, increase the resolution slightly (keep doing so until it looks good on the TV)
- Try plugging your Chromecast into a power socket, rather than using the USB power
- Try using the HDMI extender with the Chromecast to see if that makes the video less choppy – especially if you are using the HDMI connection adjacent to the Chromecast device because you can get power interference
- Ensure that you aren’t downloading or copying files across your wifi connection as this can slow the connection down and make audio and video choppy
- Try connecting your computer to the router via a cable instead of wifi to reduce the traffic on the wireless interface of the router
- Finally, if you are an advanced user, you can access the hidden settings of Google Chrome to reduce the bitrate, framerate and other such settings to reduce the amount of data required to transmit data to Chromecast to make the audio and video less choppy

Also, if you are broadcasting the entire screen from Chromecast and it’s choppy or has bad audio, you can install RealPlayer Cloud to fix the problem. After you’ve installed RealPlayer Cloud, set up a cloud location that is your local drive, then cast straight from the “cloud” (local drive) and it will play your downloaded movie cast as if it was through a tab instead of the entire screen – this will work better because it won’t have to worry about the resolution, it just plays the file 🙂

Also, if your Chromecast is slow because lots of other people are using your wifi network, then consider buying a wifi access point (wifi AP) to connect to your router, then set up another wifi network just for the Chromecast to connect to. For best results, have the wireless AP plugged into your router with a cable and position the wireless AP as close as you can to your Chromecast, to give it the best signal.
Of course, this is only useful if your wifi bandwidth is being used up, not your internet bandwidth 😉

Today I discovered that sometimes Chromecast’s audio can be kind of jittery if the Chromecast connection to the TV isn’t great (wiggle the USB and HDMI cables going into the TV). Sometimes jitter in audio can be fixed by stopping the cast and casting the Chrome browser again. Also, rebooting the TV, computer and router can fix this 🙁

Today I had some issues with Chromecast going slow, and it was because the Chromecast was too hot.
I put it in the freezer for 30 seconds which fixed it. If I get around to it, I might buy a heatsink for it. Maybe an old CPU one might be small enough, or the heatsinks you can get for “performance” RAM might be suitable.
This issue is perhaps only one that you get in hot countries.
