Hi,
Some old posts exist about the UAC2 support for the Sound Devices USBPre2 but some problem remains.
The current status is that this sound card is supported as a USB 1.1 card in high-speed mode.
But this card is not seen as a Usb Audio Class 2 on Linux. On Mac OS X this card is recognized as UAC2.
My principal problem is that the "device descriptor" provided by the card is always a USB1.1 class
There is two modes of boot for the card (pressing the "1" button, the card is in full speed mode, without pressing in UAC2 mode)
There is only one difference between these two modes in the lsusb -v : the "bInterval" go to 4 from 1.
This is already view by Clemens on:
http://lists.linuxaudio.org/pipermail/linux-audio-user/2011-October/081275.…
In this another post, we can seen:

Strange, I have never 2 on bNumConfigurations ! Somebody can test it on its card ?
This is perhaps my problem, my card only provides one "Configuration Descriptor".
The second one is certainly the UAC2 "Configuration Descriptor".
The lsusb without 1 pressed : http://pastebin.com/8yjjASv7
The lsusb with 1 pressed : http://pastebin.com/pGFdjR4K
The usbmon trace of the insertion of the usbpre2 (without "1") : http://pastebin.com/pySC4Age
This sound card is great, it is very disappointing to not be able to used it with all functionnalities.
I search help in order to debug this problem.
I am devlopper, I can test kernel patches without problem.
Thank for any idea (or patch).

Hello,
I's like to try Linux Sampler although right at the start there's a
lscp_client_create with connection refused. System is Linux Mint 17
KDE, latest. Qsampler is: 0.2.2-5 installed from package. Thanks.
Hi all,
I may not be naming what I want to do correctly so here is the long version.
I have a Behringer BRC2000 midi controller, connected to pc through usb.
It has 108 rotary knobs and buttons that, by default, send midi signals in
midi channel #0.
One can alter the channel of each controller by entering EDIT mode and
selecting the new midi channel. This is not fast for real time operation
though.
What I would like to do is read the value of one of the buttons that the
surface offers and depending on the value of that button, (on or off) I
would like to modify the midi channel of all the controllers of the
surface. To give an example, say the button is OFF , then all the
controllers send midi data on channel #0 . Then I press the button and then
all the controllers send midi data in channel #1.
If I use the 4 buttons at the bottom right corner of the BRC2000, I can
effectively access all 16 midi channels and thus have a whooping ( 108 cc -
4 addressing buttons ) * 16 midi channels = 1664 different controllers at
my disposal.
Is there an application out there which I can program to do that?
Surely I can develop a C++ application based on jakc API to do that, but I
wonder if there is something ready out there. If something like that does
not exist, would anyone be interesteed in developing it?
Thank you for your help.
Hi
I'm thinking about protecting my data with encryption. I know it's a
complex matter, and very hard (impossible?) to make a system 100%
protected. And I must admit I don't fully understand the technical
workings of the various available tools, but I found
https://wiki.archlinux.org/index.php/disk_encryption.
Now I'm wondering:
1) Can anyone share hands-on experience with a particular strategy, why
did you choose that particular tool, is it easy to setup and work with
in every-day use?
2) Most importantly: How will the various methods affect my systems
ability to perform under realtime conditions (jack) including
reading/writing files from a DAW?
NB: I'm running debian stable, if it matters...
Cheers

I just saw some amazing improvement on this laptop (2GHz, 2G RAM, dual-core, >5 years old) by recompiling kernel and glibc in Debian Testing (Jessie) with optimizations for this CPU. Overall responsiveness is wonderfully better, 48 KHz began working well, and stability arrived at 5.33 ms latency in Jack (previously 15-20ms...). The current Debian Testing made the glibc recompile much more straightforward than I've ever seen it, and I have written it up here:
http://notes.ponderworthy.com/rebuild-glibc-optimized-for-your-cpu-in-debia…
I don't usually go quite that deep into sysarcana, if any of you out there have improvements I'll love to have them and will make sure readers know where they came from if desired :-) Cheers to all!!!!!

Hey list!
So a local haunt I work at frequently doing any number of things, including sound, playing or sitting in for someone, maintenance, repairs, installs, etc. great little place in Placerville, CA.
I'm looking for input for these items directly (please go offline or start another thread if you want to talk about unrelated stuff);
Audio / video live streaming
- post mix audio to web interface with synced video.
-coverage of all in minimum of apps but some control over general mix (pgm) (master comp/EQ only if needed) and video basic adjust (contrast, luminance, phase, etc.
- network side bandwidth / bs quality ...min bandwidth / network management issues - MTU, adjust for max glitch less thruput.
Hoping to reach maybe 200 ppl via interwebs... Interactive chat - video return with possible audio availability.
As an aside, I'm starting a sound school at the premises in the new year. Guess what I'm gonna promote in the recording / PC sound management segment?! The ears prick up immediately in the circles I run in when I speak of totally NON reliance on proprietary ( spell - expensive ) OS and awesome audio apps!!
All ideas toward
Active examples would be awesome. Pls peeple... I don't want to be a jerk about
(on topic stuff - I'm prolly the last one who should speak ... Some of the stuff that comes up is just distracting for me personally. I come here for audio upon Linux info. Not lectures on how to behave or what my opinion should be! Hopefully, with as much tact intended as possible here, I speak not just for myself?)
I eagerly await technical
Ideas on this. Ty in advance. I'm really excited about this project and it's potential.
Cheers!

This is the first time posting to the mailing list, I appreciate any help that is given. I have a 2 soundcard configuration: An SB live and Gina from Echo audio. The Gina only provides audio, which is the main card I wish to use for routing my audio signals. The other card is an SB live intended for using the midi interface (MPU 401 or something to that effect), and to load a soundfont into the cards internal synthesizer. My question is, how do I use the SB live's soundfont synthesizer capabilities and route it to the Gina for audio playback. I'm using Jack and do not know how to do this. I'm wondering if it is even possible. I do not want to use the SB live's audio output jack just to hear the soundfont I loaded. I would like the Gina to handle all audio connections. Thank you again and I appreciate any help with this issue. Let me know if more information is needed.
Aw, snap!
Wait, there's no big deal (nor chromium's) cosmic (mis)alignment
being announced here now. Rest calm. Sorry to delude some of you :)
But, there's one (notable) leap on this tiny side and part of the
universe... (or is it a multiverse? move along...) What I really want to
tell is all about this happening and none else's freaking business:
Qtractor 0.6.4 (baryon throne beta) is released!
Release highlights:
* Punch-in/out over loop-recording/take modes (NEW)
* Latch/momentary MIDI Controllers toggle mode (NEW)
* JACK client/port pretty-name (metadata) support (NEW)
* Custom style and color themes (NEW)
* Mixer strip multi-row layout (NEW)
* Muted audio tracks monitoring on playback (FIX)
* Clip fade-in/out resize on time-stretch (FIX)
As for the clueless (as if there's any):
Qtractor is an audio/MIDI multi-track sequencer application written
in C++ with the Qt4 framework. Target platform is Linux, where the Jack
Audio Connection Kit (JACK) for audio and the Advanced Linux Sound
Architecture (ALSA) for MIDI are the main infrastructures to evolve as a
fairly-featured Linux desktop audio workstation GUI, specially dedicated
to the personal home-studio.
Well, although this being yet another milestone--if one may call it
that way--it also makes it official (yes, deeply engraved in stone) and
definitive as a migration to Git can be, as for source-code control and
management (it's a dirty job I know, but someone has to do it, right?).
Nevermind. It's done.
Meanwhile, please, don't ever hesitate to ask whether any of the
above does affect you some way or another. Or maybe anything else, yay?
Indeed, the puzzled you feel, the better :)

editor drop-down lists, whether available.
- Clip/Take/Range... input dialog values are now properly sanitized as
long to prevent invalid take/folding ranges.
- Audio capture/export file type default now set to "wav".
- Extending punch-in/out over loop-recording/takes modes.
- Make audio tracks monitoring always flow while playback is rolling,
independently of their mute/solo state.

- Transport auto-backward feature now honoring last position playback
was started.
- Introducing brand new application user preferences on
View/Options.../Display/Options/Custom style and color themes (eg.
"KXStudio", by Filipe Coelho aka. falkTX).
- Mixer widget gets automatic multi-row strip layout.
- Clip fade-in/out now follows time-stretch resizing, via
shift/ctrl+click and drag one of its edges.
- Fixed a typo causing FTBFS when VST plug-in support is explicitly
disabled (./configure --disable-vst).
