डिवाइस और ऑपरेटिंग सिस्टम सेटिंग्स (Device Audio Settings)

Windows, Mac, Android या iPhone पर माइक सेटिंग्स ठीक करने के तरीके:

Hindi Support

Default Input Device Selection

सही माइक को डिफ़ॉल्ट चुनें

Ensure your USB or Bluetooth headset is chosen as the default input device rather than an inactive webcam or internal mic.

सुनिश्चित करें कि सेटिंग्स में आपका हेडसेट या कॉलर माइक चुना हुआ है, न कि कोई पुराना वेबकैम या निष्क्रिय माइक।

App Privacy Permissions

ऐप प्राइवेसी सेटिंग्स की जांच करें

In Windows Privacy & Security or macOS Privacy & Security, ensure "Microphone Access" is turned ON for your browser.

Windows या macOS की Privacy सेटिंग्स में चेक करें कि आपके ब्राउज़र (Chrome/Safari) को माइक इस्तेमाल करने की अनुमति है या नहीं।

Acoustic Mesh Cleaning

माइक के छेद (Acoustic Port) की सफ़ाई

On smartphones and laptops, clear lint and dust gently from the bottom mic hole using a soft dry brush.

मोबाइल या लैपटॉप के निचले हिस्से में मौजूद माइक के छोटे छेद में जमी धूल को किसी सूखे मुलायम ब्रश से धीरे से साफ़ करें।
