Bug 263419 – [gnome-overlay] gnome-extra/gnome-media-2.26 : enable awesome new sound preferences control

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Alexandre Rostovtsev (RETIRED) 2009-03-22 21:28:38 UTC]

One of the most advertised and most awaited new features of Gnome 2.26 is the new pulseaudio-based sound preferences application and applet: http://library.gnome.org/misc/release-notes/2.26/#rnusers.volume

The current gnome-media ebuild in the gnome overlay is written in a way that makes it *impossible* to compile the new sound preferences application, no matter what USE flags you choose. In addition, the "alsa" USE flag is completely misleading.

Problem 1: to enable the new sound preferences, it's not enough to add --enable-pulseaudio in configure (simply doing that will have no effect on the end product); you must also disable the legacy volume control. The current ebuild always enables the legacy volume control, making it impossible to use the new sound control.

Problem 2: the "alsa" use flag is a lie. The legacy volume control (gst-mixer) uses gstreamer, not raw alsa. 

Problem 3: a USE flag usually represents *added* functionality. But in the current ebuild, enabling the "alsa" flag (and, by the way, alsa flag is enabled by default in desktop profiles) instead *subtracts* functionality (disables the awesome new sound preferences application and applet).

The solution is to eliminate the misleading "alsa" USE flag, and add a "pulseadio" USE flag that controls the --enable-pulseaudio and --enable-gstmix configure switches.

Created attachment 185907 [details]
pulseadio-ified gnome-media-2.26.0.ebuild

Corrected ebuild for gnome-media-2.26.0

USE="-pulseaudio" builds legacy gstreamer volume control application and applet
USE="pulseaudio" builds new pulseaudio sound preferences application and applet

Fixed in overlay, thanks for reporting.

[Comment 3 Tommaso Pasini 2009-03-23 21:52:39 UTC]

The bug is NOT fixed, even in the overlay.
The ebuild in the overlay enables always gstmix, which causes the new preferences application not to be built; as explained by alexandre, pulseaudio support and gstmix support have to be mutually exclusive.

The ebuild attached here works fine, the one on gnome overlay doesn't.

[Comment 4 Alexandre Rostovtsev (RETIRED) 2009-03-23 22:07:10 UTC]

Bug is not fixed. Please read the comments.

You need to change

--enable-gstmix

to

$(use_enable !pulseaudio gstmix)

Gstmix and the new pulseaudio sound preferences are mutually exclusive, you cannot build both at the the same time.

/me mumbles about horribly broken build logics

Fixed, thanks again.
