Thank you for your reply, i just discovered this -listdev by looking at the
help page.

Re: [PD] Raspberry Pi - Audio in and out, low latency

[Miller Puckette]

"audiodev" and other device selecting options (MIDI for example) count the
devicesstarting at 1 (probably because the first OS I ran Pd on did it
that way but I don't even remember now).  invoke "pd -listdev' to see what
devices Pd actually thinks it can access and how it numbers them.

Hi,

thank you for your replies. Of course I know man, but honestly i didn't
bother to read it...

I did try '-audiodev "1"' (my card shows up as card 1), but it didn't work.
I'll try again tonight.

Cheers,

Pierre.

on unix systems, about each and every cmdline tool has a manpage.

$ man pd

most programs i know, also accept a "-h" or "--help" argument, that
gives you another help.
Pd is a bit exclusive here, as it uses the "-help" syntax (but then Pd
is clever enough to give you the full help whenever it encounters an
argument it doesn't know about; so "pd -h" and "pd --help" work fine
as well).

$ pd -help


in the case of Pd, the manpage is a little neglected, but at least it
directs you to "pd -help".

yes, but only if you consider Pd-0.35 relatively new (which even i
don't :-))

i guess "-sounddev" is rather unknown, because the documentation only
mentions "-audiodev".

the two flags are really the same, and i suggest to use "-audiodev" to
avoid more confusion.

no, it's not new.

pd -h give you all needed informations. you don't need a web access.

That's great (and surprising) news... I wonder why you're getting a better
ride from teh E-MU box than I am from the iMic but it sounds as if I should
be digging up one like yours to try.

I think you can just invoke 'pd -sounddev 2' to select the USB device.

I don't know why it's working. I just hope the next update won't break that!

So "-sounddev 2" should work for my card showing up as card 1 ?
Incidentally, there are only two pages that I know of on the web explaining
how to use start-up flags in the command line (
http://en.flossmanuals.net/pure-data/getting-started/starting/ and
http://puredata.info/docs/faq/commandline).  None of them mention
"-soundev". Is this a new flag ?
Unless there's a better place on the web to learn about start-up flags, i

website. I always find it frustrating when i have to spend a lot of time
figuring out how to use a command line program just because i don't know
the syntax of the arguments.

[PD] Raspberry Pi - Audio in and out, low latency

[Pierre Massat]

Dear list, dear Miller,

I tried Pd on a fresh Raspbian install today. I removed pulseaudio as you
suggested. I installed Pd from the Raspbian repos (not your version).
I tried it with my USB E-MU 0404 soundcard. It worked right away. No need
to slow down the USB.
I tried with a latency in Pd of 10 ms, in X, connected to the internet, and
there was very little dropouts.
This is so promising it's scary.

Now i have one very frustrating problem : i don't know how to choose my
soundcard from the command line when starting Pd...
It shows up as Card 1, device 0 when i do "aplay -l", but i don't know how
to use this information.

Cheers!

Pierre.
