Follow these checks in Audio Fix →When this guide applies
Windows setups that visibly expose separate Stereo and Hands-Free profiles. This is a call-volume check, not a microphone repair.
Connection scope: Bluetooth. Symptom: Sound changes during calls.
This is a documented check, not a diagnosis of your equipment. The model name does not confirm the selected input, mode, software or connected partner.
If your exact model or a required setting is unknown, use the “I don’t know” branch below. Do not apply a similarly named model’s instructions.
Checks and possible outcomes
Start at check-0. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.
check-0
Does Windows expose separate Stereo and Hands-Free entries?
Use only entries actually shown for Pi8. If your Windows version uses a different interface, stop at the unknown or unavailable branch.
Look for: Confirm the stated observation; do not infer an unavailable detail.
- If Yes / this check is completed → Is the quiet symptom occurring during a call?
- If No / the check cannot be completed → Keep the last observation for support
- If I do not know / cannot check → An observation is still unknown

check-2
Inspect the call application volume
Check its playback-volume control at a comfortable level; do not raise every system output to maximum.
Look for: Perform only this check, then choose whether it could be completed.
- If Yes / this check is completed → Was the intended Hands-Free volume target confirmed?
- If No / the check cannot be completed → Keep the last observation for support

check-3
Was the intended Hands-Free volume target confirmed?
If using system volume, confirm it controls the Hands-Free call profile rather than the previous Stereo entry. Observe the next normal call; do not place an unwanted test call.
