Hallo, Fernando Pablo Lopez-Lezcano hat gesagt: // Fernando Pablo Lopez-Lezcano wrote:
You could try using the alsa plug interface which can do format conversions (including interleaving and de-interleaving), but I seem to remember that the current pd alsa code does not let you use generic alsa device names but just card numbers which correspond to the hardware interface (I may be wrong here).
Fortunately you're wrong at last: the latest Pd from Miller's site, pd-0.37-1test6, supports setting the alsa device as a string again by using the new "-alsaadd" option. So this:
$ pd -alsa -alsaadd plughw:1
should work. It thus is possible to define arbitrary alsa devices in ~/.asoundrc to use in Pd like these:
pcm.pdhw { type hw card 1 }
ctl.pdhw { type hw card 1 }
pcm.pdplug { type plug slave.pcm "pdhw" }
Then play with -alsaadd:
$ pd -alsa -alsaadd pdhw $ pd -alsa -alsaadd pdplug
Of course a lot more device definitions are open to Pd now. The RME surely will need some fiddling to get it to work in Pd.
Here's some links for setting up a decent asoundrc for the RME cards (I don't own one):
