maemo.org - Talk - [ANNOUNCE] CSSU-thumb thread

do we actually need esound-compat for anything? apt-get seems to be fine with deleting it (no packages depend on it), but with dependencies you never know.

does any program actually use esd?

IIRC i read somewhere its for network sound in XDMCP sessions...:confused:

should not be required. obviously with XDMCP you'd need a way of getting "network transparency", but pulseaudio does that.

AFAIK no programs use esd anymore. The only rdependency of pulseaudio-esound-compat was libesd0 (in extras/testing/devel), which, for all I care, is not used by anything (I don't even have libesd0 installed).

If at some point some program would use esd (why?) then it will pull libesd0, which in turn will pull the pulseaudio-esound-compat, so no problemo here :)

Tested it with locked frequency, and still it seems to use a little more CPU than it should (although, hard to be sure, as difference isn't big - 1-2% - and xorg doesn't use much in idle, anyway).

Do you think it's worthwhile to recompile it for cssu-thumb, like pulseaudio? Also what are supposed benefits of parameter mentioned by you (-O3 -ffast-math -ftree-vectorize)? Maybe increased CPU usage is worth it, if we gain something else?

Sorry, no idea about those compiling parameters here, so question may be silly :)

Had anyone the experience that alarms didn't sound after upgrading PA packages? Even if i had rebooted 1x after update, not one of my test alarms gave a sound, not on 'silent' nor on 'Normal' profile. Only after the second reboot everything went back to normal.
(Btw: IIRC this happened to me at least 3-4 times before...)

Those are optimization parameters. O3 is very aggresive, and requires user-engaging-brain before using (you may want to search for info on pointer aliasing). fast-math will make some floating point operations faster, at the cost of losing strict IEEE floating point compliance (no biggie for most purposes, but again, user needs to know what he's doing). tree-vectorize will attempt to use parallelizing instructions (sse2, neon, etc.)
