OSS finally....

[coreplayer2]

I had to dig out an old laptop to test on but OSS apps and x86_64 modules finally resurrected, patched, built and speakers playing that familiar osstest music once more on tc-7.2 corepure64  :p


Just in time for TC-8.x right?  Oh My!!    Well, on that thought I have used the minimum of patches to update the src for 4.x Kernels.  At this point it shouldn't be much of an issue to build modules for up to 4.8 Kernel
Patched with
4.x kernel patch
gcc-5 patch
oss install script patch created myself (not sure if I'll submit upstream because am not positive how POSIX compatible it is and also not sure if there's an upstream to sent it too)..

Only need to figure out and test the Flash support module symlinks and build the 32bit version.  Then,
need folks to test I guess..

[Juanito]

Well done 

[hiro]

there's an OSS forum with people still responding, i'd put the patches there.

[coreplayer2]

Status repoport on OSS

All OSS extensions for both TC-7 x86 & x86_64 repo's completed

Also getFlash_beta extensions (Flash v24.x) updated with OSS support for both TC-7 x86  &  x86_64 repo's completed.
 
Maybe we'll have to see the new year in before uploading them in the repo's

[hiro]

good work, coreplayer2! having an easy choice between the two sound systems is always good.

[coreplayer2]

Anyone tried  OSS yet??

Suitable for older equipment I guess..
 

Thanks for trying

[Juanito]

Does oss support hdmi?

Normally "aplay -l" (I loaded alsa after oss) should show an hdmi device.

[coreplayer2]

I don't believe so, but i could be wrong..

I have the same issue on my latest and greatest desktop, but OSS work fine on an older notebook.

[hiro]

are you trying to use oss modules at the same time with alsa modules? i don't think that should work

[Juanito]

The oss modules were loaded first - I only loaded the alsa modules after oss did not work.

..but, yes, normally there would be an hdmi device available with alsa, so maybe the oss modules somehow blocked that.

[hiro]

I'm not sure about hdmi, I don't have tc on modern computers with these interfaces. But I do know that digital audio output via spdif works fine via oss. It's the individual driver's responsibility. If your card isn't supported it's unlikely that will change. Old stuff often works though.

[Juanito]

I never use hdmi, so it's something of a pain:

* hdmi is the default alsa device (which makes no sense on a laptop)
* I cannot get sound with Xvesa (the i915 module needs to be loaded with Xorg)

[hiro]

that i915 has to be loaded is horrible. hard to imagine the kind of people that are responsible for this
are there some usable docs? perhaps you could implement the driver for OSS
