PT2314 seems to work with 5V power supply #2

I started to use PT2314. I bought this one. This documentation says that the minimum power supply is 6V. However I have applied 5V from Arduino Uno and it seems to work.

Because I do not have any 6-10V under my hand I just came with the idea that I can attach just 5V to PT2314 and at least to check if the I2C interface is working with your library. The I2C interface worked fine with 5V so I was able to set volume, gain, channel and so on. I was surprised when I've heard the music from the speakers (I've attached RDA5807 tuner and PAM8403 amplifier).

Ah nice! I'm also notices that this chip works nice with 5V power supply. I'm using this chip inside a DAB radio with my own control board. And that manufactured pcb supplied by 5V - so, yes, never trust datasheets :)))

I think we can close this issue now. We can keep it in mind as a known issue.
