KA17 playback is wrong specifically with MQA/DSD and EQ is positively enabled. Local controls are confirmed and SPDIF OFF for analog headphones.
Look for: Confirm this exact setup and observation before continuing.
- If Yes, I confirm → Accept a temporary USB playback interruption?
- If No / my setup differs → Continue with source and model support

Accept a temporary USB playback interruption?
Changing EQ OFF can interrupt USB playback and alter level/tone. Continue only outside calls/recordings with agreement to pause and reduce headphone level first.
Look for: Explicit informed acceptance is required before the next action.
- If I accept these effects → Pause the source
- If No / leave this unchanged → Continue with source and model support
- If I cannot confirm → More information is required
