Can't play Hulu shows -- error P DEV320
I got the P Dev320 error anytime I tried to watch The Great or any other Hulu original. Other TV shows and movies played fine but all Hulu originals threw up that error. I tried all the prescribed troubleshooting and none of it worked.
As weird as it sounds, what finally worked for me was going into Settings>Display Type and changing the display setting from "automatic", which included HDR10, and changing it to the setting that matched the resolution of my TV without HDR. Then, I restarted the Roku and went back into Hulu after the reboot. I don't know, maybe Hulu originals are incompatible with HDR or something but it worked and I've finally been able to watch season 3 of The Great.
Thanks for letting us know, arrmo.
Since you've already done all of the troubleshooting steps provided to no avail, we highly recommend reaching out to their Customer Support for further advice regarding this matter. Please be advised that they run a different operating system inside the Roku streaming platform. So, it may be possible that you are not having any playback issues from a different device. It's best to reach out to them for clarification and further assistance. You can also contact their direct line at 1-888-265-6650.
We're hoping to get everything sorted out soon and appreciate you bearing with us in the meantime.
Kind regards,
CarlyI looked up the menu on a TCL Roku tv. It looks like if you select SETTINGS from the main menu, and then select TV PICTURE SETTINGS then that might put you in the right place. If there is an option for (may say) Automatic 1080p HDR10, UNSELECT that option and choose just 1080p TV or 720p TV. It would appear that the HDR (high dynamic range) is what's causing the issue. I pray this helps. 😊
I actually found the root-cause to these issues. It's not what you might think. The remedies people post online seem to be short-term fixes, and not a solution. More than likely you are connected to a multi-band access point supporting a variety of radio frequencies. I've posted the root-cause on both Hulu and Roku communities, and tried to explain what's happening in laymen's terms. No more band-aid housekeeping; resetting, reinstalling, rebooting anything. I found the fix on 02/14/2024, and so far to date, Hulu works 100% on every load request. I have several Roku TV's, as-well-as 40+ other devices on my home network, and the solution I posted in those communities has worked ever since. Hope this helps.
Welcome and thank you for posting here in the Roku Community, HoneyMay4046!
It is highly appreciated that you've brought this to our attention and we'd be more than happy to suggest some troubleshooting steps to help you reboot the Hulu channel.
Is this an isolated case within the Hulu channel only? If so, kindly follow the steps provided below precisely to work:
- Remove channel: navigate to your Home screen, move to the right, highlight the app, press Star*, then select Remove channel
- Perform a system reboot: navigate to your Home, select Settings > System > Power (skip if unavailable) > System restart
- Re-install the channel: navigate to your Home, scroll and select Store, look for the channel, then press Add channel
For reference and further information, kindly visit our Support article on How to resolve a channel playback issue.
If the issue persists, we highly recommend reaching out to the channel provider themselves as they are the ones who provided and maintained their channel on the Roku streaming platform. Their channel may need an update and you can reach them on their official Support website.
We hope you get everything sorted out soon so you can get back on streaming Hulu and we'll be looking forward to your update. Hope this helps!
Best regards,
