Hi Community member,
Please let me confirm my concern as below.
[My concern]
I have summarized my concern to the subject as this post . AIC3254 did not reflect in the Flag register of "HPL powered up" even though the HPL PGA register was powered-down.
So, would you please double check whether this problem will occur in your side?
I summarized the reproduced method with using AIC3254EVM-U as below.
[ Re-produce Procedure]
1. Connect the AIC3254EVM-U to PC
2. Run the Typical Configuration of Playback.
* There is not relationship of Typical Playback Configuration mode for this issue. Please choose one configuration by yourse3. lf.
3. Open the Status Flags and select the "DAC Flags". And push the "poll" button on this window.
4. Open the "Analog Output" window, and select the "Headphone Outputs" tab.
5. Power down the HPL PGA with checking the Status Flags.
For your information, when powered down the HPR PGA, this status Flags worked well.
If you have any question, please let me know.
Best regards,
Kaka
