I am looking for audio amplifier with outputs for headphone, speaker, and output, which indicates, that headphones are pluged in (or an amp, which can automatically switch between headphone (when they are pluged) and speaker ). And this amp must have I2C interface to control volume.

Hi Anton,

TLV320DAC3100 (or TLV320DAC3101/TLV320DAC3120 depending on your requirements) is a DAC that features Headphone and Speaker outputs.
It also has an ADC for headphone detection purpose, an interrupt can be enabled for headphone detection; you can change the output stage based on the interrupt.

Best regards,
