Beep generator works well before entering to standby.
After exiting standby mode there is audio but Beep generator doesn’t work.
Any recommendations ?
void HP_Standby(bool set){
if (true==set)
DA7212_CLR_REG_BITS(DIALOG7212_SYSTEM_ACTIVE,DA7212_MASK_ACTIVE);// Standby
else
DA7212_SET_REG_BITS(DIALOG7212_SYSTEM_ACTIVE,DA7212_MASK_ACTIVE);// active
}

Hello,
I will look into this for you. Are you using the DA7212 Eval board?
Kind regards,
Elliott Dexter
I have the DA7212 Eval board, but we are using our hardware.
Please check the standby ON/OFF while generating Beep tone on the Eval board and let me know if the Beep is still working after exiting standby.
If yes, please send the script.
Hello,
Would you be able to send me your set-up script?
Kind regards,
Elliott
I don't have a set-up script , not using the Eval board
The setup for the beep generator works without the standby.
After entering to a standby end exit standby, the only part that doesn’t work is the beep generator.
It looks like a bug since all the other functions are operating and there is no need to configure the registers again.

Hello,
We have test the beep generator on our eval boards and cannot replicate the issue. I have attached the set-up script we used.
Can you ensure that before going into standby, that all audio paths are disabled including the Tone genarotor.
Kind regards,
Elliott
Tone Generator and Standby issue
Exit from Standby generate a noise, I tried to disable the audio paths, but it doesn’t work as expected. Below is the code to set the CODEC into Standby, please send a tested code to enter and exit Standby and keep the tone working.

Tone Generator and powerup Issue
Upon powerup (no JLINK) the Tone Generator is not working!
The Tone Generator works only while the CPU is connected to a JLINK!
The only way to work around this issue is to reset the CPU again after powerup reset and initialized the CODEC again.
There are no differences between the registers values before and after the 2nd reset.
