My idea is that an other half with enchanced audio capabilities would be a great addition for future other half concepts. Although I'm not sure whether it is truly possible to make such other half, it could provide at least a decent digital to analog converter (DAC) with built in amplifier to support use with high impedance headphones. In addition if original hardware does not support Apt-X Lossless bluetooth, it could be added to use of other half's high grade audio capabilities on various bluetooth devices. Maybe battery might need some upgrading too in order to compensate use of more power hungry electronics. At least the idea of having a "audiophile" other half is very interesting.

I'm not an expert, but I'm afraid the i2c is not fast enough for this. Please correct me if I'm wrong.

I'm not sure about the current capabilities of Jolla hardware either, but if it is possible anyhow it would be great.

Well, I guess it could at least have an amplifier that would plug to the headphone jack. On the other hand it would be probably be ugly as hell and I'm not sure where you would put the jack for the amplified output. :)

If i2c is too slow for real-time playback then.. well, think old-school, gravis ultrasound style :) Some memory, some suitable MCU and a DAC. Decode your mp3/flac/whetever, push it to the memory trough i2c and let the MCU+DAC do the playback from there. Complicated, sure.

Bluetooth HQ-Audio would be an option, @onion is right, HQ audio via I2C is practically impossible.
