Tool/software:
I'have an application with a LM49450 chipset.
When using the chipset with speaker the is no problem, but when i plug the headphone,
the i2c communication bus crashed when i try to change the headphone volume (or try to send any other i2c command).
Any idea?
I notice that when charge pump is bypass, i2c access is correct but the headphone output audio doesn't work.
