FFADO 2.0 Release Candidate 1 (1.999.40) available

The FFADO team is proud to announce the first release candidate for FFADO 2.0.

This release candidat is intended to collect feedback about the library under wide-spread usage. The code should be free of major bugs. It is recommended that you have a basic amount of experience with Linux and with building software before you try to install this.

We are looking for packagers that are interested in creating packages for their favourite distro.

An elaborate changelog can be found below.

Please review this package thoroughly in order to spot potential problems. Feedback on distribution aspects and documentation is also welcome.

libffado?

This release provides the libffado shared library that provides a unified programming interface to configure and use all supported devices. Currently this library is used by the 'firewire' backend of the jack audio connection kit sound server (http://jackaudio.org). This backend provides audio and midi support, and is available both in jackd and it's multiprocessor variant jackdmp. (note: At the moment there is no support for ALSA nor for pulseaudio.)

Access to the device internal configuration (e,g, internal mixer) is exposed using the ffado-dbus-server daemon. This daemon exposes the configurable parameters of all detected devices through DBUS. The ffadomixer application in support/mixer presents a basic GUI to control these parameters (only for officially supported devices).

Features

  • 24-bit audio input/output (unlimited number of channels)
  • supports for all sample rates a device supports
  • MIDI input/output (unlimited number of channels)
  • Support for S/PDIF and ADAT/SMUX I/O
  • Support for external sync (e.g. Wordclock)
  • Internal mixer and device control support for all officially supported
    devices (NOTE: no support for internal effects DSP)
  • Support for device aggregation (limited to devices on the same bus that are synced externally)

Usage feedback

This release introduces an option where you can identify your device as being used on Linux with FFADO. You will be asked whether you want to submit your device information to ffado.org. The reason this feature is present is to convince the supportive vendors that their cooperation pays off, and to convince the other vendors that Linux users are a market. A secondary advantage is that we can keep track of what versions are used by how many people.

Therefore we would like to ask everyone to perform this registration. No personal data is transmitted (except for an optional email address). The IP address of the submitter is saved to help recovery in case the database is bombed with bogus data. However the address is first processed by one-way MD5 hashing it, such that it is not recoverable and privacy is secured. This usage information is of enormous importance for future device support. The aggregated statistics are available here: http://www.ffado.org/?q=usage.

Motu users beware

RC1 breaks Motu support, got bitten by this myself and found a post on the mailing list telling me to use beta7 instead. Which works perfectly fine for me (828mkII). So Motu users: stick with beta7

As a side note, the ffado-mixer apparently reports my vendor id and product id as "unknown", so I'm holding off registering my device for now. Is there any way to manually input the brand and model?
