Dear Team,

I've been facing this nagging Input Mic issue in Win 11 Pro machine ever since I bought this laptop.

Laptop Model: Acer A325-42 (AMD Ryzen 7730U).

Please see the image for the Audio info. acer

The problem: The Mic Input detects the Mic but it won't work.

Privacy>Mic: Access is ON; Let Apps access is ON.

acer-snd

When I test the sound, the volume bar doesn't dance what I use Test, and it only records hissing noise!

I do not understand what's the issue here. The same Headset works perfectly with phones as well as tablet. I badly need this Mic Input function to work with a few Apps such as Duolingo etc on this Windows laptop.

Kindly guide me to resolve this issue.

Thanks & Regards,

Sunny

    Hi, Sunny Acer

    The microphone is detected, but the hissing and inactive level meter suggest that Windows is receiving the wrong input signal. The screenshots also show a different Realtek driver version from the one offered for this Acer model.

    Here are some suggestions you can try:

    Disconnect the headset. Open Device Manager, expand Sound, video and game controllers, right-click Realtek(R) Audio, and select Uninstall device. If available, select Attempt to remove the driver, then restart the laptop.

    Install the audio driver listed specifically for the A325-42 from the Acer driver-download page, even if Windows previously installed a newer version.

Please make sure that you completely understand the risk before retrieving any suggestions from the above link. 

    Open Realtek Audio Console and, under Device advanced settings, make sure the analog jack is configured as Headset, not Headphones.

    In Settings > System > Sound > Microphone, keep Audio enhancements Off, select the microphone, and run Start test. Also confirm Let desktop apps access your microphone is enabled.

    If it still records only static, test a USB headset. That will help confirm whether the laptop’s 3.5 mm combo jack is faulty.

    Thank you for your patience in reading, I hope this information has been helpful to you.

    Hallo, Kai-H!

    I appreciate your response.

    Well, I was successful with the Acer OEM Realtek suite install, however the same hissing sound comes out. Please see the images.

    This is what Copilot says:

    You did everything right — the OEM driver is now installed (6.0.9686.1), but since the mic still only produces hiss, that confirms the problem isn’t just driver mismatch. At this point, the evidence points strongly to a firmware/BIOS mapping bug in how the Acer A325‑42 routes TRRS mic input. Playback works because that’s universal, but the mic pin isn’t being interpreted correctly by the laptop’s audio codec.

    🔎 What this means

    • Drivers are ruled out: You’ve tested both Microsoft’s generic Realtek driver and Acer’s OEM package. Same result.
    • Hardware is ruled out: Your headset mic works fine on phones/tablets.
    • Remaining culprit: The laptop’s combo jack firmware/BIOS logic for TRRS mic detection.

    Next steps

    Test with USB audio A small USB sound adapter or USB headset bypasses the TRRS jack entirely. This is the most reliable workaround.

    Escalate to Acer support Share your screenshots (driver versions, mic test results). Acer may provide a patched Realtek driver or BIOS update.

    Check BIOS updates Sometimes Acer silently fixes audio routing bugs in BIOS releases. Worth verifying if a newer version exists.

    Try Microphone Array In your Sound settings screenshot, there’s also a “Microphone Array (Realtek Audio).” Test that input — sometimes Acer maps the headset mic incorrectly under “Array” instead of “Microphone.”

    📌 Inference: Since both OEM and Microsoft drivers give the same hiss, the mic routing failure is baked into firmware. The only permanent fix will be an Acer‑issued BIOS/driver patch. Until then, a USB adapter is the practical solution.

    Would you like me to draft a support escalation note for Acer with all your screenshots and findings, so you can send them a complete package without rewriting everything yourself?

    Unfortunately, I don't have any other devices to test so I must order.

    I also tried the Microphone Array (please see the above uploaded images). This time there wasn't any hissing sound either! A simple audio setup shouldn't give me this much pain. :(

    This laptop was delivered on 1st Nov, 2024 so it's out of warranty.

    Please suggest what to do in my case.

    Thanks & Regards
