Thank you for the feedback.
[quote]- The speaker volume does not change when I connect headphones. This is odd, as I would expect the speakers are turned off when headphones are connected - as it happens in most other players[/quote]This is because there is used resistor voltage divider to attenuate the speaker signal for the headphone output. So a simple switch-over is not possible in the headphone socket.
[quote]- When pushing the volume up or down buttons, a klicking / scratching sound is hearable. It’s not a big deal, but it is a bit annoying.[/quote]Indeed, there is this minor click sound. I’m sorry, this seems to be a feature of the audio codec and can’t be avoided.
