PS4 Controller RB Button Stops Working After First Buttonpress on Android TV

[nathanielatom]

I have an issue on Android 10 TV (Lineage OS running on Nintendo Switch) where a PS4 controller's RB Button only works once and then stops working on all subsequent presses. Other controllers (Switch Pro controller and Joycons) continue to work. The PS4 controller works normally in Steam Link and other apps.

Steps to reproduce

1. Launch Moonlight on Android TV with a PS4 controller paired.
2. In Steam Big Picture tap RB (which works and pulls up the chat interface), then tap RB again which proceeds to do nothing. Also occurs streaming any game.

Other Moonlight clients

• The issue does not occur when using Moonlight on PC/Mac/Linux (including L4T Switchroot Ubuntu 18.04)

Moonlight settings (please complete the following information)

• Have any settings been adjusted from defaults? No
• Does the problem still occur after reverting settings back to default? Yes

Gamepad-related issues (please complete if problem is gamepad-related)

• Do you have any gamepads connected to your host PC directly? No
• If gamepad input is not working, does it work if you use Moonlight's on-screen controls? Not available on Android TV AFAIK
• Does the problem still remain if you stream the desktop and use https://html5gamepad.com to test your gamepad?

Device details (please complete the following information)

• Android version: [e.g. Android 10] Android 10 TV Lineage OS 17.1
• Device model: [e.g. Samsung Galaxy S21] Nintendo Switch Nvidia Tegra X1

Server PC details (please complete the following information)

• OS: [e.g. Windows 10 1809] Windows 10 21H2
• GeForce Experience version: 3.26.0.154
• Nvidia GPU driver: 526.98
• Antivirus and firewall software: N/A

Similar to #1144 but different controller, localized to a single button, and based only on first press independent of time.

Hmm, this is very peculiar. We don't change any of our logic based upon whether we got an RB button press or not. FWIW, I just tried a PS4 controller on an Android 10 device (Galaxy Note 9) and it worked correctly. However, Linux support for DualShock controllers has substantially changed in kernel updates over the years, so it may be kernel version dependent.

Is your controller connected via Bluetooth or USB?

Can you try https://html5gamepad.com/ while streaming and see if the RB button stays pressed after the initial input or if it is released normally and never can be pressed again?

Also please try a gamepad test app like https://play.google.com/store/apps/details?id=ru.elron.gamepadtester to see exactly which inputs are registered when using the RB button.

If possible, please also collect a logcat log from your device when trying to stream.
