The input devices may not be recognized anymore due to a variety of reasons. It could be due to a hardware issue such as a faulty connection or a malfunctioning device. It could also be caused by a software issue such as outdated drivers, conflicts with other devices, or a system update that has disrupted the recognition of the input devices. Additionally, it is possible that the input devices themselves have become damaged or are no longer functioning properly. Troubleshooting the hardware and software components of the system can help identify and resolve the issue. **

To determine if the PC input and output devices are not working, you can check for several signs such as no sound coming from speakers, keyboard keys not responding, mouse cursor not moving, or display not showing any images. You can also try troubleshooting by checking the connections, restarting the devices, updating drivers, or testing the devices on another computer. If these steps do not resolve the issue, there may be a hardware problem that needs to be addressed by a technician. **

If you are connecting a turntable, you should use the phono input on your receiver or amplifier. The phono input is specifically designed to work with the low-level signal produced by a turntable's cartridge. If you are connecting a device such as a CD player, smartphone, or computer, you should use the line input. The line input is designed for higher-level audio signals and will provide the best sound quality for these devices. **

To switch an AUX input between two devices, you can use an AUX switcher or a manual switch. An AUX switcher allows you to connect multiple devices to one input and switch between them using a button or a dial. A manual switch involves physically unplugging the AUX cable from one device and plugging it into the other. Both options provide a simple and effective way to switch the AUX input between two devices. **

You can connect two audio devices to one aux input by using a headphone splitter. A headphone splitter has one male end that plugs into the aux input and two or more female ends that you can plug your audio devices into. This allows you to share the aux input between multiple devices, such as two smartphones or a smartphone and a tablet, and play audio from both devices through the same aux input. Just make sure to adjust the volume levels on each device to avoid distortion or imbalance in the audio output. **

No, the AV input cannot be used as a microphone input. The AV input is designed to receive audio and video signals from external devices such as DVD players, gaming consoles, or cameras. A microphone input requires a dedicated port that is specifically designed to accept microphone signals, typically labeled as a "mic in" or "audio in" port. Using the AV input as a microphone input may not work properly and could potentially damage the equipment. **
