Taeko sound problem - headphones work, speakers not

I recently purchased the SOF sound driver from your website to enable audio on my Lenovo Flex 5i Chromebook (model: Taeko, CPU: Intel i3-1334U), currently running Windows.

While the driver installation completed successfully, I’m experiencing an issue:

  • Audio works through headphones when selected,
  • But no sound comes from the internal speakers when switching the output to “Speakers”.

Could you please advise on how to resolve this issue?
I would appreciate your help in getting the speakers working properly.

Thank you in advance for your support.

I have the exact same problem both on TAEKO i5-1334U and i3-1315U. @tgurcik Did you found a fix?

After installing MaxxAudio now it says

The device cannot start. (Code 10)

The specified firmware image is invalid.

I have the exact same problem. support is bad, it takes too long to respond to emails. I also can’t hear it on the speaker, only through headphones.
