Read MoreThere is feedback from customers that when the GY404C voice chip is used, every time the motherboard is powered on, it will issue an instruction to set the volume to level 20. However, when it is actually used at the site, there will be feedback from terminal customers that the volume of the machine has become louder. This is What is the situation and how to analyze this problem?
In fact, except for a reset command, the probability of software being reset in other situations is very low, at least it has not been encountered so far.
Hardware, this is the most likely, please check it first.
For example: the 5-pin 3.3V capacitor of GY404C is placed incorrectly or is missing, especially when playing music, causing the voltage to be lowered and reset.
For example: it is possible that the power input voltage of pin 4 of GY404C is too low, causing a low voltage reset.
If you really can’t find the cause, you can contact us to have the function of remembering the volume after setting it.
In other words, when the user sends a command, the GY404C chip stores the memory, so that even if the GY404C is reset every time, the volume will be the memory volume, and it will no longer be the maximum level 30.
At the same time, because most application scenarios require the highest volume, we designed the volume to be the highest by default every time it is powered on, without memorizing it. You can adjust the volume or the amplification factor of the power amplifier, which is also possible, as shown below.
