Hmm, if the client side is calling snd_pcm_open_noupdate() this means the app is using ALSA directly and thus has no need for soundwrapper in the first place.....

Does it run OK without soundwrapper? If so, then I'd just nuke it.

i didn't try, but it shouldn't segfault anyway, right?

it works without it, though, indeed, i'll commit the change

fillets-ng does work without soundwrapper, and that is fixed.

however, i reproduced the soundwrapper segfaulting with another game: quake2

i'll try to get a usefull backtrace from it

backtrace from running with quake2:

Again, this is soundwrapper + direct alsa support which makes no sense, but I agree to the point of principle that it should not cause crashes directly...

I'll take a look, but please fix quake2 to not run soundwrapper too :) (/me doesn't really play games so don't have it installed).

hold on, hold on...

iinm, quake2 runs on OSS...(/dev/dsp) and i have no sound from it at all... and it's configured to run without soundwrapper...

Hmmm, that's a very confusing backtrace then, as this is clearly using alsa calls...

I wonder if soundwrapper is not working with pulse and instead running in "alsa" mode.... in other words rather than running padsp, it's running aoss... That would explain things (and perhaps I misdiagnosed fillets too?)

Can you maybe test running aoss and padsp directly? If the former crashes but the latter works, then this is possibly pointing at where the problem is :)

i'm not sure how to test that? (do you mean, using that command like soundwrapper?)

also fillets had sound without it, quake2 doesn't have sound

Assigning to maintainer now that our maintainers database has an entry for

Summary: fish fillets game fails due to soundwrapper segfaulting => some games fail due to soundwrapper segfaulting (fillets-ng, quake2)

For mga cauldron I'm going to introduce osspd soon and deprecate soundwrapper. I'll leave this bug open for the time being, but osspd is going to be the recommended configuration for legacy OSS support in mga2. With any luck we'll get mmap support in there too :) Watch this space.

pinging. because nothing happened to this report since more than 3 months ago, and it still has the status NEW or REOPENED

@ Colin

Please set status to ASSIGNED if you think this bug was assigned correctly. If for work flow reasons you can't do that, then please put OK on the whiteboard instead.

soundwrapper is still in cauldron (at least Sophie says so)
ossp (OSS (Open Sound System) Proxy Daemon) is in cauldron too

Last revision of ossp:

@ AL13N

Do you still have problems?

Just for reference the mmap support in osspd is not yet available, so some legacy games won't work all that well, but such is life.

There have been discussions in the last couple days about people looking at mmap support in fuse and the kernel such that osspd can use it, so by the time mga3 rolls around this will likely be the recommended solution.

Hi,

This bug was filed against cauldron, but we do not have cauldron at the moment.

Please report whether this bug is still valid for Mageia 2.

Thanks :)

Cheers,
marja

Thanks all :-D

I'm not sure soundwrapper can be fully deprecated until osspd can use mmap (there are some patches kicking around for it).

i'm closing as old
