USB Speaker for Pi 3

what do "lsusb" and "dmesg" have to say?

In the spirit of 'if I wanted to get to there, I wouldn't start from here' frankly the inbuilt sound on a Pi is awful

I had great success with a hifiberry audio DAC hat and there are some that even have small power amplifiers

Just add passive loudspeakers..

Or use e.g.

(which is what I have) to a normal set of PC speakers using a phono plug to 3.5mm jack adapter.

Do you have the correct cable for a Pi3? 4-pole jack on the Pi end.

Have you tried amixer? amixer cset numid=3 [0|1|2] where 0 is auto, 1 is analog (jack), 2 is hdmi (digital)

I've no illusion as to the quality of the sound, all I need it to do is make a noise.

Ooh, that might work ! I'm already using the GPIO bus, but hopefully that won't be a problem (SDA/SCl and BCM 6, plus 3.3V power). The three inch speakers ought to be big enough, and I've got enough space available for one of those (two if that is what is needed).

I did consider that, but part of the problem is that I've not got a lot of space to play with, and even a small set of speakers might me too big, particularly if I've also got to find space for a multiplug for a power supply. Relocating the Pi would be a non-trivial task.

Why USB? A Pi will do audio out without any extras, apart from perhaps a small analogue amplifier. Certainly well enough for a tiny speakers.

pretty awful PWM s**te tho IIRC. Not sure whats down the end of the HDMI port either.

?Progress is precisely that which rules and regulations did not foresee,?

a reasonable start

do you need to put these audio things in config.txt ?

lots of hits, no obvious answers

That used to be the case, but they improved it immensely. Certainly good enough for "just a sound". OP should simply use the 3.5mm jack and el cheapo active PC speakers. (They must be active because it's a headphone plug, not a normal line amplified signal.)

Perfect digital audio. Quality depends on the DAC and speakers on the other end. If you have a "receiver" (amp which has hdmi inputs) then a ?10 Pi Zero (and a mini-hdmi to hdmi adapter...) is good enough for hifi audio.

In message , Dave Liquorice writes

My reading up on this before I started was that I would need an amp of some description if I used the audio out, and space is limited, particularly if I need to add in an extra power supply, so a basic Pi powered is preferred.

tiny

(as in they have built in amps) PC speakers is fine. The OP states he's not after "HiFi" and is limited on space for speakers...

What ever is shoved in at the other end. Rip a DVD/Blueray without reprocessing/transcoding/reencoding WHY you get was on the disc.

tiny

Quite a number of Pi powered DAC solutions some with on board amps. For tiddly speakers and non-HiFi you don't need masses of power or high voltage (ie > 5 V) power rails. 4 V (to avoid clipping and have a bit of headroom) into 8 ohms is 2 W or so, more than enough.

USB for power. 3.5mm jack for sound.

cheapo speakers will be about 80dB per watt at one meter. That's still

70dBm at 100mW.

That is loud talking level.

Another "not what you asked for" post, but might a cheap battery powered bluetooth speaker do the trick? E.g.

Which I've just tried on my RPi4, but I don't see why it wouldn't work on a RPi3.
