Hello. I'm baffled and looking for help. I've been trying to play

... But if you want audio quality you might find you prefer using ALSA.

aplay -L

will list playout devices. I'd hope your system can then find the
required device. Usually Pulse will send out via ALSA anyway.

Thanks, but ... I _think_ I've ended up telling alsa to go out via
pulse. I do not like configuring linux sound. I never have, and it
doesn't seem to have got any more comprehensible since the last time I
looked ... I seem to have something that works and that'll do for now. I
may find more tuits for it later.

OK, that's fine if it is working correctly. Although I suspect in practice
Pulse is actually then sending out via ALSA as it tends to sit 'on top' of
it. If you want quality, though, check that the output sample rate reaching
the *playing hardware* is following the rate of the source material. Pulse
has a habit of mangling everything into 48k sample rate.

TBH setting up ALSA is usually pretty simply for playout. The problem is
generally the lack of documentation. But for future reference there are
pages on my Audiomisc site that explain how to set up ALSA for quality
audio replay. The hardest bit can be stopping Pulse from then 'nannying'
you and changing what you set.

I have had trouble with ALSA/Pulse (I've never got on with linux audio
backends, it's one of my least favourite things about it). I've been
fiddling intermittently with this for a while and not getting it right, it's
likely I've got some odd configurations hanging around as a result. Pulse
insisted on coming into the mix because it seemed to offer the possibility
of doing what I first thought of, pushing audio from the client machine. Now
I see that that doesn't work, I'd probably do best to wipe the raspberry and
set it up again from a clean start; at which point I'll bear that in mind.

Thanks.

The DAC has a little row of lights showing the incoming sample rate. I just
set something playing and had a look ... none of them are lit up. Helpful,
no ? :-/
