If it's the same as the previous models: no, the audio of the Raspberry Pi is pretty rudimentary (it uses PWM) [1]. However, you can use an external DAC to improve this.

- augustk 11y agoA couple of years ago I bought a Raspberry Pi 2 to use as a music server. However, when playing through a Benchmark USB DAC I hear pops and clicks in the audio. Instead I bought a Cubox and use its Toslink output which works perfectly. Does anyone know if the USB audio issue have been fixed in the third version of the Raspberry Pi?
- mindslight 11y agoConnecting the analog audio of the RPi (1B) to my receiver causes the receiver's CPU to slow down to the point where it is unusable! It looks like the RPi puts out a DC-biased signal, and the receiver is seriously lacking input robustness. The two devices were also connected via HDMI, ruling out ground issues. I've since moved the music setup to also use HDMI (the DAC in the receiver is bound to be better anyway), but sheesh, be warned.
- justin66 11y agoHow on earth do you know what your receiver's CPU is doing?
- mindslight 11y agoThe UI slows down gradually until the whole thing is unresponsive, reproducibly. IIRC disconnect the analog input, and the UI picks right back up. I've no idea if it's a priority interrupt firing too much, body diode current weirdness, or some thermal issue. And I'm certainly not going to keep teasing the fault to figure it out.
- justin66 11y agoYeah, wow. That's wacky.
