Ubuntu 26 – Microphone produces distorted input on ChatGPT and YouTube

Support and Help
1

Hello Ubuntu community,

I’m using Ubuntu 26, and my microphone is recognized by the system:

arecord -l
**** CAPTURE Donanım Aygıtlarının Listesi ****
kart 1: Generic_1 [HD-Audio Generic], aygıt 0: ALC256 Analog [ALC256 Analog]
  Altaygıtlar: 1/1
  Altaygıt #0: subdevice #0

However, when I use voice input on YouTube or ChatGPT web apps:

  • The microphone works, but the audio quality is very poor.

  • Words I speak are misinterpreted or distorted.

I know the microphone is detected by the system, but it doesn’t work correctly through the browser.

My questions:

  1. What are the current recommendations for making the microphone work clearly and correctly in browser-based applications (ChatGPT, YouTube, etc.) on Ubuntu 26?

  2. Which PulseAudio or PipeWire settings should I adjust?

  3. Is a tool like pavucontrol necessary, or are there more modern solutions?

I’m looking for practical and up-to-date advice. Thank you!

Ubuntu 26? The 26th release of Ubuntu was Ubuntu 17.04 which is ’ancient’.

Adjust the microphone volume setting first and check if it is not too loud or too soft. You might see an option for “microphone boost”, start testing in the first place with the boost off.

Yes, pavucontrol is the tool to adjust the microphone volume in the soundserver.

(There is also alsamixer, or more modern QasMixer to adjust the volume in the driver, but I don’t think you’ll need that. Maybe only as a last resort)

How is the audio quality use other applications?
How is the audio quality if you merely record your voice locally?
