Hello all,

I'm sure this has probably been asked dozens of times before but I was unable to find the right answer after searching, so if it has, I'm sorry.

Anyways, I am using slackware -current now and I downloaded and compiled kernel 2.6.13 a few days ago. I have everything working beautifully with the exception of programs that still need OSS sound, for example flash.

Programs that use ALSA work fine, all my users have access to the audio group and I set up mixing to allow multiple processes simultaneous access to sound. I have the ALSA drivers compiled as modules and as far as I can tell I have the OSS compatibility modules setup as well, however the only way to get an OSS dependent program to use sound is to run it through the aoss program. I'd like to be able to not have to prefix that to every OSS program though if I want sound.

If I reboot into the -current vanilla 2.4.31 kernel, I do not have to use aoss. OSS programs seem to work fine there with ALSA, so I am obviously missing a step somewhere in my 2.6.13 setup, I just don't know what I missed.

Here are the kernel modules my system loads at bootup:

Which OSS programs are you trying to run? I might be wrong but I don't think you need the OSS enabled in the kernel as alsa uses alsa-oss to provide the necessary "workaround" for them.

I have a very similar setup as you, Soundblaster Live! sound card and such, but I DON'T have OSS enabled in the kernel. If I can test the program(s) you are using to see if I can get sound then maybe we can put this puppy to bed.

Well flash files in firefox are the main thing at the moment I'm using to test with. If I boot into the vanilla 2.4 kernel flash will have sound right off the bat, however booting into my custom 2.6 kernel, flash will not have sound unless I run firefox through aoss by typing "aoss firefox".

You may be right, maybe the system is trying to load native OSS modules and it's conflicting with ALSA-OSS compatibility. I will try recompiling later with OSS completely disabled and only have ALSA and the ALSA-OSS compatibility modules selected.

Before you recompile, which sites in particular?

Later,
MMYoung

homestarrunner.com is the one I test flash sound with as it is the most flash heavy site I visit.

Had sound, kinda' funny, I've never heard of that site before.

BTW, I using kernel 2.6.11.12 and, as I stated, I don't have OSS configured at all. Here is sound part of my config file:

Also here is what is in my /usr/lib/firefox/plugins directory:

flashplayer.xpt* libmozsvgdec.la* libtotem_mozilla.so*
libflashplayer.so* libmozsvgdec.so*
libjavaplugin_oji.so@ libnullplugin.so*

The libjavaplugin_oji.so is a symlink to /usr/lib/java/plugin/i386/ns7/libjavaplugin_oji.so*

HTH,
MMYoung

Had similar sounding problems for quite some time.

Found that doing: works a treat.
No such luck with konqueror though.

Also, sound is slightly latent.

I apologise if this is not relative to the ACTUAL, I merely skimmed and felt the need to post as the artsdsp soluton (for me) is not commonly known (at least hard for ME to find it!)
