Wireless Music Player Using Atmega32 - ATMega32 AVR
https://atmega32-avr.com/wireless-music-player-using-atmega32/
Our wireless music player allows the user to listen to uncompressed digital audio streamed over a wireless link. The music player reads uncompressed audio data from an SD card in an immobile “base station.”. A pair of Xbee transceiver modules are used to stream data and control signals between the base station and a portable module.
AVR 16bit Stereo Wave Player - ATMega32 AVR
https://atmega32-avr.com/avr-16bit-stereo-wave-player/
This project aims to implement a cost-effective wave player based on AVR (ATmega / ATiny Series) with CD-Audio Quality, which can play 8-bit/16-bit Mono/Stereo standard RIFF (Resource Interchange File Format) wave files. This project can be applied into many applications such as bus / subway auto-annoucing system, elevator voice indication system. …
MP3 Player Using Atmel Mega103L - ATMega32 AVR

Digitally outputting audio is nothing more than outputting analog samples at a specific rate. However, consider the size of raw audio data. The absolute minimum samplerate (imo) would be 8kHz (and this sounds terrible for anything but speech). If using 8bit samples, one second of audio will need 8KB of flash storage.
WAV player using ATmega8A - Audio - Arduino Forum

Can I able to play 44100Hz sampled audio in ATmega8 or at least 16KHz sound using either of the methods? Well 44100Hz no. As to 16KHz possibly both but your problem is reading in the data. It is possible you could store it into external EEPROM on the I2C bus but it would be far cheaper getting an ATmega 328 chip.
