[Regression] sound stopped working in VirtualBox

[diver]

hrev48487.

I can't hear any audio in this revision. Booting to an older hrev48482 fixes it.

In hrev48482 sound starts only after playing mp3 file for 5-10 sec.

Audio still works in VMware Fusion 7.1.0 with OpenSound driver in hrev48487.

The libgame.so change in that rev range seems unlikely to be related..

Ideas:

• might be corrupted settings; dsuden sees that fairly often: he deletes all media-kit related files in config/settings after shutting down media_server, then reboots to have them recreated to their normal out-of-the-box state, and things work again. Theoritically it should be possible to control/review them in MediaPrefs, but some are "hidden" in the OutputMapping tab, some might simply be more subtle corruption ..etc; we never got enough data on that bug to file a ticket on it..
• other than that, might be the "butterfly effect" I see with #11497, where non-functioning sound can take 2 or 3 different forms and crawled up on me slowly with each pkgman update, until I couldn't get it to work any more..

Please try to get a backup of the corrupted settings files if possible, that could give us some information (and ideally provide a fresh/working settings file for the same machine). As we discussed with Diver on IRC, the changes in that revision range can't be related to the issue, so it's something else, either corrupted settings, or the buildbots doing strange things leading to disfunctional media kit.

Ok, and now sound is back in hrev48500. Hmm..

Could be the 'butterfly effect' thing then (I mean sensitivity to tiny changes, including the ordering of package activations), rather than the settings. For comparison purposes, here's what I experienced in the month of november, before sound went out for good in december:

• sound would be 'on' or 'off' randomly after pkgman up's
• sound would come back when deleting the administrative/activated-packages and rebooting (i.e. no update involved, just resetting the already existing update); at least first time I tried, if not the second.
• sound would go on or off if doing a pkgman up and then coming back to the previous hrev that was installed before (don't remember for sure how I accomplished that, since there is no officially sanctioned way of reverting that I know of; I think out of desperation I had preserved a full copy of one hrev's set of file and typed "pkgman install *.hpkg" within that folder or something :-P)

Anyway I've given pushing on that lead, now I'm hoping for the "worms armageddon" lead to be fruitful for Adrien instead ;-) ..

If you're seeing problems on recent/powerful hardware it gives more validity to pushing on this lead I suppose.. more than if it was just impacting old pentiums and core2 and stuff.

(In #11666) Removing #11650 as that problem is now well understood. Adding #11610.

[pulkomandy]

Is this still a problem?

[diver]

Seems to be fixed now...
