[PD] ESI Gigaport HD+ on RPI
hi all, someone added the ESI Gigaport HD+ as a not working sound card few days ago on http://puredata.info/docs/raspberry-pi I'm quite surprised because this sound card is USB Audio Class 1 compliant and USB spec version 1.1 compliant and also fully compatible to USB 2.0 host controllers Moreover, I had a confirmation this sound card works on Linux and it's previous version ESI Gigaport Ag works on the Pi. Thus i was thinking Gigaport HD+ will work on the RPi; Who made the test ? Could you tell me more about the setup ? (mainly if you use a USB hub or not) Cheers a -- do it yourself http://antoine.villeret.free.fr ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] direct connection from pd to webrowser, low latency
If you are looking at the audience carrying smart phones.. I recently worked a on a project where we wrote a custom OSC Android app that sent control data to the patch and an app called SoundWire that received audio on the phone and ran in the background. All communication was over a WiFi network we setup. Latency did obviously exist but it was manageable. The audio server app runs on Linux and Windows (no OSX unfortunately) and can have multiple devices connected to it. http://georgielabs.99k.org/SoundWireHelp.html I'd be happy to share more details if required. -Varun -- Twitter: @ntkeep re-sounding.com http://re-sounding.com designingsound.org http://designingsound.org pd-list-requ...@iem.at mailto:pd-list-requ...@iem.at 27 April 2013 11:00 Message: 1 Date: Sat, 27 Apr 2013 14:13:14 +0800 From: Simon Wisesimonzw...@gmail.com Subject: Re: [PD] direct connection from pd to webrowser, low latency To: pd-list@iem.at Message-ID:517b6c7a.6060...@gmail.com Content-Type: text/plain; charset=ISO-8859-1; format=flowed On 27/04/13 05:38, o...@onyx-ashanti.com wrote: On Apr 26, 2013 10:08 PM, katjakatjavet...@gmail.com wrote: Hi Onyx, What is your aim, do you want to entertain your (physically present) audience via smart phones instead of PA system?

Re: [PD] ESI Gigaport HD+ on RPI
I can't report about that but I have another compliant USB 1.1 interface, Edrol UA25, which I've never been able to get to work with a pi. So I think this is confirmation that that can indeed sometimes happen (if it were just one of us perhaps it could have been a fluke). cheers M On Sat, Apr 27, 2013 at 11:18:06AM +0200, Antoine Villeret wrote: hi all, someone added the ESI Gigaport HD+ as a not working sound card few days ago on http://puredata.info/docs/raspberry-pi I'm quite surprised because this sound card is USB Audio Class 1 compliant and USB spec version 1.1 compliant and also fully compatible to USB 2.0 host controllers Moreover, I had a confirmation this sound card works on Linux and it's previous version ESI Gigaport Ag works on the Pi.

Re: [PD] ESI Gigaport HD+ on RPI
Hi Antoine, The one I added is the HD (not HD+). This one has the same casing as the 'AG' so was hopeful but no, nada. Initially thought the one I tested was broken as there was no sign of it on the pi. Plugged it into my debian lappy and boom - all recognized and working. Pah. Currently sat on the 'not sure what to do with pile'. It would have been great; 6 outs for not much money (plus the recycling redundant technology thing). You seem to have had good results from the 'UDJ' card which seems to be currently the other choice for multiple audio outs on the RPi?

Re: [PD] ESI Gigaport HD+ on RPI
Sorry, Just noticed the question about the hub: No hub - not sure why you're asking but if it's relevant the Pi was connected to 5.2v/2a power cable, and running most recent firmware.
