Hi,
not actually a chiptune so don't wanna to upload it here and contaminate the data-base, hahaha,
but I acquired lately a Raspberry Pi and this is my very first song made on it. 
https://soundcloud.com/yerzmyey/yerzmyey-ursula-part-2
The song has been made entirely on Raspberry Pi 2. Also, it has been recorded directly from the machine.
22 channels have been used.
Generally, the R_Pi's sound is being generated by the Broadcom BCM2835 chip (for model '1' of the R_Pi) and by Broadcom BCM2836 chip (in model '2' of the R_Pi) - and in my case it's the BCM2836 chip - so it's resolved somewhat like in ZX Spectrum: the sound is being generated by CPU.
It works with 11 bit quality. It's not an actual DAC, it is a digital PWM module (gives a 'pulse width modulated' signal) working with frequency around 40MHz and it is low-pass-filtered.
The funny thing is, I also rendered the song directly into harddisk and compared it to the version recorded from real R_Pi: and I deleted the rendered file to hell, haha. The original Pi sound is warm'n'soft; doesn't remind thousands of razors.
Byezzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz!
