ప్రశ్న 1
A Windows PC has both built-in speakers and USB headphones connected. Sound is playing through the speakers, but the user wants all normal playback to use the USB headphones. Which action is most appropriate?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
• Windows Sound settings allow the user to select the device used for audio output.
• Selecting the USB headphones as the output device directs normal playback to that device.
• Microphone permissions and printer settings do not determine which device reproduces sound.

A microphone works correctly in one Windows application, but another supported app reports that microphone access is blocked. The microphone hardware and driver are functioning normally. Which Windows configuration should be checked first?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
• Windows provides privacy controls governing whether supported applications may access the microphone.
• A functioning microphone can still be unavailable to an application if the relevant access permission is disabled.
• Because the hardware already works elsewhere, replacing the microphone or reinstalling unrelated devices is not the best first action.

System sounds and most applications are audible, but one media application produces no sound. Which Windows feature should be checked before reinstalling the audio driver?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
• Windows Volume mixer can maintain volume and mute controls for individual applications.
• If only one application is silent while other sound works, that application's mixer setting is a logical first check.
• Reinstalling the entire audio driver would be unnecessarily broad when system audio is otherwise functioning.

Audio worked normally until a recent audio-driver update. Immediately afterward, sound became distorted. Device Manager shows that the previous driver version is still available. What is the most targeted troubleshooting action?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
• Driver rollback restores the previous driver when a recently installed driver causes a problem and the earlier version is available.
• The timing of the symptom directly after the driver update makes rollback a targeted diagnostic action.
• Formatting Windows or changing printer services would not directly address the identified audio-driver change.

Explanation:
• A disabled audio device cannot provide normal playback even when its hardware is physically present.
• Device Manager allows an administrator or authorized user to enable a disabled device.

One corrupted or stalled document is blocking subsequent documents in a Windows printer queue. The printer itself is online and otherwise functioning correctly. Which action is the most appropriate initial response?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
• Windows allows individual pending print jobs to be cancelled from the printer queue.
• When a specific stalled job is blocking later jobs, removing that job is a targeted first troubleshooting step.
