- poglet 3y agoSo if you need 3.5mm output you need to buy some accessory? That's disappointing - reminds me of what happened with phones.
- jlarcombe 3y agoi still won't buy a phone without one! i wonder how long i'll be able to hold out...
- andrewstuart 3y agoRemoved the audio jack, what the? That's a fundamental misunderstanding by the hardware designers of what Raspberry pi is. Raspberry Pi has jumped the shark.
- squarefoot 3y agoThe audio output from all Raspberry Pis has always been crap, to the point anyone looking for decent quality would have been forced to use an external DAC anyway, so not a big loss here, although stopping that PWM audio generation nonsense and adding the DAC into the CPU would have been the right thing to do.
- gsich 3y agoNo. The pins are still there. My guess is most peole don't have a need for it.
- danbee 3y agoThe audio jack on Raspberry Pi's has always been terrible quality anyway. Ok in a pinch but it's not a huge loss. If you want quality analog output from a Pi you need a DAC hat.
- alden5 3y agoIf you're using a pi you're already in a pinch, putting a dac on a pi seems alot like putting lipstick on a pig, the only scenario where it wouldn't be overkill is music streaming and i highly doubt thats even a majority of pi projects with audio
- spacechild1 3y agoYou can plug a 5€ USB audio adapter. That's what I have always been doing.
- jlarcombe 3y agoprobably the way to go, but 'another thing to plug in' if you're building something for someone else to use
- spacechild1 3y agoYou need to plug in the headphones/speakers anyway, so it is just a little piece in between :)
- notatoad 3y agothat definitely sounds like a whinge. raspi is fundamentally an unfinished, everything-not-included product. most use cases require some sort of dongle, hat or other adapter. an audio jack (especially in a context where you're not using an HDMI device that you can get the audio from) is much more niche than a lot of other things that aren't included on-board, like storage or POE. if it's a trade between a built-in audio jack or a built-in RTC, i'll take the RTC 100% of the time.
- jlarcombe 3y agofair enough, i suppose i'm interested in using it for mainly audio/music applications and so am biased. no use for an RTC. demonstrates really how hard it is to keep everyone happy! over the years i think they've traded things off fairly well.
- proompter5 3y agoCan I ask what you'll use the RTC for?
- notatoad 3y agoNo RTC means your time is incorrect until something sets it. usually NTP, assuming the device connects to the internet right away. if it doesn't connect to the internet right away, then you just get a wrong time. it means that for any device that ever reboots, there's some amount of logging that has untrustworthy timestamps. A battery-powered RTC means that any logs from the device aren't inherently untrustworthy.
- bmitc 3y agoYou might look into the Teensy boards. There's an audio adapter that adds a DAC and headphone jack, and there's also an audio library. The Dirtywave M8 was built on top of the Teensy stack. https://www.pjrc.com/teensy/ https://www.pjrc.com/teensy/ https://www.pjrc.com/store/teensy3_audio.html https://www.pjrc.com/store/teensy3_audio.html https://www.pjrc.com/teensy/td_libs_Audio.html https://www.pjrc.com/teensy/td_libs_Audio.html https://dirtywave.com/ https://dirtywave.com/
- jlarcombe 3y agoTeensy is BRILLIANT - but a bit different to the Pi. It's quite convenient to have a 'real computer' you can toy around with directly on the device.
- bmitc 3y agoI have fallen out of love with Raspberry Pi due to the performance. In desktop mode, I have found it too lacking to be any fun. It even struggles to run the web browser. And things like Mathematica, that you get for free which is awesome, are just much too sluggish to be very much fun.
- jlarcombe 3y agoYes, although it sounds like the Pi 5 will be a significant step up in this regard. To be honest for what I was doing, Pi 4 was easily good enough. It was just a bit more convenient to be able to get media assets etc on to the device directly, implement a simple UI, etc etc.
- Applejinx 3y agoIt's a pity about Teensy3 being effectively gone. I've got numerous eurorack modules based on the Teensy3 12-bit onboard analog output. The trick there is twofold: one, if you're doing traditional digital audio, this output has a very 'old school sampler' sound that takes well to further processing. It's a really primitive output with a lot of character that sits well in a mix or performance: no trouble building an entire mix around sounds coming off this output. Two, because it's directly built into the Teensy and doesn't have as many intrinsic assumptions about what digital audio is, you can overclock it to sample rates as high as a megahertz or so, while still running the same audio library. That means if you're just putting out a square wave, the ONLY limitation on your quality is aliasing, as bit depth no longer matters. If you're doing multiple square waves you still don't need full use of the 12 bit analog output to do it. And if you're at 1mHz aliasing is next to nothing, so all of a sudden your cheesey 'bad' output is in fact shockingly good. Even waves which do require the 12 bit resolution are a lot better with no significant aliasing. I run four-note chords with two oscs per note, portamento, and additional waveforms, on a single Teensy, at upwards of 300kHz. From what I can see, no audio hat does this. They're all mediocre CD quality. I'm sure you could build a ladder DAC out of raw digital outputs on a more modern Teensy and do just as well, especially if you ran even lower bit than 12 bit. Teensy3 has that analog pin just right there, though. Lovely :)
- idonotknowwhy 3y agoSo I guess this means no composite out either. What a useless device this has become
