How can I fix Hulu Plus PB4 errors?

1. Edit your registry

If you’re getting Hulu Plus PB4 error, you might be able to solve it simply by modifying your registry.

According to users, this problem occurs because a set of older drivers made some incorrect changes to the registry.

To fix the problem, you need to manually edit your registry by doing the following:

Press Windows Key + R to open the Run dialog. Enter regedit and press Enter or click OK.

In the right pane, double click on DisableProtectedAudioDG. If this DWORD isn’t available, you can create it by right clicking the right pane and choosing New > DWORD (32-bit) Value from the menu.

Set the Value data to 0 and click on OK to save changes. If using Value data 0 doesn’t fix the problem, you might want to set it to 1 and check if that solves the issue.

Many users reported that modifying this DWORD fixed the problem for them, so be sure to try it out.

Several users claim that you can fix Hulu Plus PB4 simply by disabling default HDMI sound and setting Speakers as the default audio device.

According to them, this issue occurs after connecting the second display with their PC via HDMI.

This causes the HDMI sound channel to become the default device and this error to appear. To fix the issue, you just need to set your speakers as the default audio device.

This is rather simple and you can do it by following these steps:

Right click the sound icon in the bottom right corner and choose Playback devices from the menu.

Right click the empty space and make sure that both Show Disabled Devices and Show Disconnected Devices options are checked.

Right click Speakers and choose Set as Default Device.

In order to fix this problem, you need to remove Hulu and install it again. To do that, follow these steps:

When Settings app opens, go to Apps section.

Now select the Hulu app and click on Uninstall.

After removing the app, you need to download it again from Windows Store and check if that solves the problem.

If reinstalling the application doesn’t help, you can always reset it by doing the following:

Select Hulu app from the list and click on Advanced options.

Now click on Reset button.

Click on Reset button again to confirm.

After resetting the application to default, check if the problem still appears.

If you are running Windows 8 through a virtual machine, like VMware or Parallels or maybe using this device through a partitioned computer such as a Macbook, chances on getting the PB4 error are much higher.
