If you're experiencing issues with the ConsumerIrManager on an HTC M8 running Android Lollipop, there could be several reasons for this problem. The ConsumerIrManager is an Android API that allows devices to transmit infrared (IR) signals, typically used for controlling remote devices like TVs and air conditioners.

Here are some steps you can take to troubleshoot the issue:

  1. Check if the device has an IR blaster: Not all devices have an IR blaster, even if they support the ConsumerIrManager API in their software. Ensure that your HTC M8 model has an IR blaster hardware component. You can usually find this information in the device's specifications or user manual.

  2. Verify software support: Android OEMs can modify the Android operating system and sometimes disable certain features like IR functionality. Check if your HTC M8's specific Android version and software build support the ConsumerIrManager API. Unfortunately, some manufacturers may choose to remove or disable IR functionality in their software updates.

  3. Test with third-party apps: Try using third-party apps from the Google Play Store that are designed to control IR devices. Some of these apps might work even if the stock ConsumerIrManager API is not functioning correctly on your device.

  4. Check for software updates: Ensure that your HTC M8 is running the latest available software update. Manufacturers often release software updates that may address issues and improve the device's functionality.

  5. Reset app preferences: There might be a glitch with the app preferences that are affecting the ConsumerIrManager. You can reset app preferences by going to Settings > Apps > (menu button) > Reset app preferences. Keep in mind that this will reset preferences for all apps, so you may need to reconfigure some settings afterward.

  6. Contact HTC Support: If none of the above steps work, it's possible that there's a hardware or firmware issue with the IR blaster on your device. In this case, reaching out to HTC support or visiting an authorized service center could provide further assistance.

  7. Alternative solutions: If your HTC M8 doesn't have an IR blaster or if the built-in IR functionality is not working, consider using alternative solutions like external IR blaster accessories that plug into the device's audio jack or Bluetooth-enabled smart home hubs that can control IR devices.

Please keep in mind that the availability and functionality of the ConsumerIrManager API can vary depending on the device model, Android version, and software modifications made by the manufacturer. Additionally, my information is based on knowledge up to September 2021, and there may have been developments or changes since then.
