Other Parts Discussed in Thread: TLV320AIC3254
Dear Team,
our customer would like to use the TPA6166A2. On their prototype board they reported following problem:
They connect a cable with 3.5mm TRRS plug which simulates a headset (HPL,HPR,GND,MIC) to the TPA6166A2. If they do not insert the plug fluently then most of the time TPA6166A2 reports a mono headset with HPL on ring 1 as detected accessory. When they change the Short_Z setting (bit 7 of register 0x18) from 4 Ohm to 7 Ohm then the issue is gone. However, it is not clear to us why the issue should be gone by changing that setting. Can you provide me details of the automatic detection process of TPA6166A2?
What we already tried:
- Reducing the debounce time from 3ms > 20ms
- Change the FAST bit so that the polling runs @ 300ms vs. the default 2s
Nothing helped.
Please find below the connection to the jack.
Looking forward to your feedback.
Best Regards
Martin
