[ANN] Summer'15 release frenzy pt.2 - Qsampler 0.3.1 is out!

by Rui Nuno Capela

The Summer'15 release frenzy continues... ;) On the wake of LinuxSampler 2.0.0 release [1], Qsampler 0.3.1 is out!

Also worth noting is that Qsampler [2] is now raked as a genuine Qt5 [3] application, leaving Qt4 behind but still an option. Qsampler [2] is a LinuxSampler [1] GUI front-end application written in C++ around the Qt [3] framework using Qt Designer.

Re: [LAD] [alsa-devel] Fw: Using loopback card to Connect GSM two way call to the real sound card UDA1345TS

by Clemens Ladisch

Srinivasan S wrote: > Am facing overrun & underrun issues, when I run the the above GSM application with the attached asound.conf The sound card and the GSM streams are not synchronized. You need to compensate for the drift between the clocks, typically by resampling. (Jack's alsa_in/alsa_out would automatically do this.) Regards, Clemens

Call for testing: new ALSA driver for Digi 002/003 family

by Takashi Sakamoto

Hi all, This is a call-for-testing of my new ALSA driver for Digidesign 002/003 family. If you have these devices, would you please test the driver with your devices and report your experience about it. Especially, I want you to test MIDI port for machine control, because developers have no 'console' models, just tested with 'rack' models. When installing and testing, please follow this instructions: https://github.com/takaswie/snd-firewire-improve Patchset was already posted to alsa-devel and confirmed to playback/capture PCM samples/MIDI messages by ALSA applications. [alsa-devel] [RFC v2][PATCH 00/11] digi00x: new driver for Digidesign 002/003 family http://mailman.alsa-project.org/pipermail/alsa-devel/2015-March/089708.html Several issues are still remained: * The port for MIDI machine control message is not tested yet, because 002/003 console model are required. * When allocates 2 or more channel numbers for the device, after 15 to 20 seconds from playbacking, any PCM samples causes noisy sound. Then, all of LED on the front panel light. The streaming still continues correctly. * The actual effects of external clock source is not clear. When set the clock source is somewhat external, even if stopping the clock source, the device continues to sound PCM samples against my expectation. * The meaning of asynchronous messages is unknown. This patchset adds a functionality to receive it in userspace. You can test it with updated libhinawa sample script. https://github.com/takaswie/libhinawa In my plan, this patchset will proposed for Linux 4.2. But these issues need to be clear till the merge-window. Regards Takashi Sakamoto

JACK sample rate pull up/down

by Reuben Martin

Does anybody know if there is any way to pull up/down with JACK? And if there is, can ALSA deal with it very gracefully? -Reuben

Re: [LAD] AVB not so dead after all

by Leonardo Gabrielli

Hello Reuben, I have been talking to a Intel guy at the last AES convention and he told me they are supporting AVB (maybe he's reading this list as well). Another strong signal regarding AVB not dead. We were specifically talking about audio networking and multimedia.
