I just recently upgraded Ubuntu from 9.04 -> 10.10
I tested all my Linux audio apps on Ubuntu 10.10
(my config is in the sig at the end of this email)
and every one checked out OK except for baudline
which wasn't working with ALSA
the reason it isn't working with ALSA - as related to me by the
developer - was that
'Ubuntu 10.10 removed kernel ALSA OSS emulation' but baudline does work
with Jack'
the kernel I'm using was compiled by Ubuntu
Linux 2.6.35-24-generic #42-Ubuntu SMP Thu Dec 2 01:41:57 UTC 2010
and I had to do the 'which kernel works with the broadcom wifi driver'
dance which is why I'm using this particular kernel
as I read more about this issue I see more clearly the lack of thinking
behind this decision
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/579300
so I have some questions to other Ubuntu 10.10 users out there:
- why was the ALSA OSS emulation layer removed?
Hello Kim,
Happy new year to you too. Even though I don't use 10.10 (I think it's
no good for audio production) I think I could answer some questions. The
ALSA OSS layer was removed for the reason Daniel Chen tries to point out
in the bugreport. But he already backed out of the discussion (which is
a nice display by the way of the contemporary, modern level of
communicating with one another).
- why is there no general mixer for all the different volumes any longer?
This is because Ubuntu uses PulseAudio by default which demanded a
different front-end to control volumes (gnome-volume-control which is
afaik a kind of stripped version of pavucontrol).
- and is there an app that replaces the old Volume control that allows
you to adjust settings on all the different audio services?
You could try pavucontrol (PulseAudio Volume Control) or ALSA mixers
like alsamixergui, gnome-alsamixer, gamix or qamix.
- is there a 2.6.xx.x kernel that has the ALSA OSS emulation layer
compiled in?
(I'll need a range of kernels so I can test/select one that works with
my Broadcom wifi driver.)
- if so, where can I find it?
Sorry, I have no idea as I don't use Maverick. You could ask Philip
Johnsson (https://launchpad.net/~philip5) if he might be interested in
building a package as he also builds multimedia packages for Maverick.
Best,
Jeremy
