Mixer: Amp Spk switch will turn off left headplug

For some reason only the right headphone speaker is working when Amp Spk is enabled. Cold that be a hardware problem due to the fact that a Freerunner only has one speaker?

  • Status changed from new to closed
  • Resolution set to invalid

Speaker and headphones are mutually exclusive by hardware design.
You must not use speaker (=switch on Amp Spk) while headset is plugged in, as hardware can not switch off left headset when speaker is active.

closing bug to INVALID.
