In general you do need this stuff. The only thing that is in the
kernel is alsa-driver...

alsa-oss and alsa-driver can be unmerged.

I'm not so sure about alsa-oss

Well, since I have oss emulation running, I can say I'm 99.5% sure you can ;)

Well, who am I to argue! I'll just hang with the other 0.5% I guess... ;-)

alsa-oss doesn't install much, but it does install aoss which has been
an interesting script to have available a couple of times. Probably
you are right and just need one or the other. I'm still not sure,
although I can say that emerging alsa-oss doesn't cost much in terms
of disk space or time so I'm going to leaveit installed.

Of course alsa-oss documentation has no information at all about using
one or the other...

Do you have the libraries installed that alsa-oss give me? (Shown below.)

Interesting info. Thanks!

I see. So alsa-oss gives more than just the oss emulation driver. Obviously, I
don't have those libraries.

What applications link to those libraries?

Thanks!

Not sure at all.

Possibly some of the functionality behind the /dev entries is what
these provide? Or maybe they are used only by aoss? Much better asked
on Alsa-dev I suppose.

I just assumed since it was there, and since the Alsa Docs seemed to
suggest it was required, that it was to be built. I used it on my
Redhat systems before coming to Gentoo.

Heh... I assumed they were just drivers (modules) but looking at what you
posted, alsa-oss are libraries; I see no modules there.

I guess I'll have to read the ALSA docs once again :)

Thanks all.

I went ahead and unmerged all alsa stuff to see what I really needed to support alsa in a 2.6 kernel. I ended up re-emerging alsa-headers, alsa-lib, and alsa-utils to get it working again. It doesn't look like the alsa-oss package is necessary but I'm not really sure how to tell. My sound seems to be working fine without it.

FWIW, those are the only three alsa packages I have, and I've been
running alsa for ca. 8 months.

Hello Collins,
emerge alsa-headers && emerge alsa-lib && emerge alsa-oss

The first 2 work, but alsa-oss pucks! Any ideas?

OK, I did some reading and now recal why this exists. Look here for
some good, but simple, info:

http://alsa.opensrc.org/index.php?page=OssEmulation

aoss gives the user the ability to use the PCM plugin layer of Alsa.
This allows the user to do software mixing of OSS applications running
under Alsa which is something I think OSS itself probably wouldn't
have allowed. I suspect that using aoss I can also route OSS apps to
different IO's on my soundcard using definitions in a .asoundrc file.
(For instance, my HDSP9652 has 26 physical inputs, 26 physical
outputs, and 26 pcm playback ports, or the AP2496 card which has 10
IOs) which would allow me to do hardware mixing in the sound card
itself.

Probably this is nothing most people are interested in, but it's made
available by aoss to those who are, and additionally might be an
option for certain OSS apps that for whatever reason have trouble with
the kernel level emulation that's made available without emerging
alsa-oss. Both can be on your system at the same time. aoss is only
used if you choose to use it. (That said, I've only done it a couple
of times and it was a long time ago...)

Cheers,
Mark

Usually signs of a fuxored ebuild; bugzilla it.

The workaround is usually 'FEATURES="-sandbox" emerge .....'.

Bugzilla and I are becoming fast friends.....
I was able to emerge 'arts'. I have kde.

I've got everything possible related to alsa turned on in the kernel
(2.6.7-r11) and have tried several players. KsCD seems to be working
as the name of this songs.... are found, but no sound comes out.

I'm upgradeing KDE now (3.3) so we'll see if that helps any.
Googling produces lots of noise on KDE + ALSA + ARTS, but not many
good ideas....

I guessing(actually hoping) I do not actually need alsa-oss?

Thanks,

James

I agree. Until Mark came up with his information, I never heard of it.

What? No RTFM? ;-) ;-) ;-)

Joking aside, I tried aoss a couple of times. I needed it to do sample
rate conversion on some OSS app while running a couple of other Alsa
apps. It worked, but it never became important to me and I just forgot
why I emerged it in the first place. I never got it to work well. On
big apps it just segfaulted on me.

I think it's not important to most people, but for some of us it might
be useful. Just another tool in the toolbox.
