Re: [PD] Raspberry Pi - Audio in and out, low latency
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 think it would be a good idea to provide more details on the community 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. Cheers, Pierre. 2013/1/22 Miller Puckette m...@ucsd.edu 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. cheers Miller On Tue, Jan 22, 2013 at 09:23:51PM +0100, Pierre Massat wrote: Dear list, dear Miller, I tried Pd on a fresh Raspbian install today.

Re: [PD] Raspberry Pi - Audio in and out, low latency
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. cheers Miller On Wed, Jan 23, 2013 at 10:56:55AM +0100, Pierre Massat wrote: Hi, thank you for your replies.
