Being lazy here, so quick question:
I'm looking for a simple way to resample in ALSA from a capture/play interface that
supports only 48kHz, to 44.1kHz which is desired.
Both playback and capture resampling is needed, and it seems I neeed dsnoop and dmix.
However, I am bewildered by the somewhat byzantine configuration of .asoundrc.
There's one card on this machine, a "SB LIVE!" (which means "48kHz
only!"), running the emu10k driver.
There's no JACK up in this at all, it's just an old streaming PC running BUTT.
There is also no PulseAudio because I avoid PulseAudio.
If I were using ices2 I suppose I could use its built-in resampling, but that's not an
option in this case.

just telling an application to use "plughw:CARDNAME" should get you what
you want.
you need to do more if you want to control which resampling quality you get.

Thanks. It seems the latest version of ALSA seems to have a default plughw interface
wrapped around on this particular card, because it "just works" at 44.1kHz and
many other samplerates too, even though we know that the hardware only does 48kHz. So in
this case the problem was simply solved by upgrading.

There's one card on this machine, a "SB LIVE!" (which means "48kHz

This card has a wavetable synthesizer, which can dynamically resample
and mix together 64 voices. You need neither resampling nor dmix.
