'''>''Could you provide a link to the Launchpad bug, so that the same
things
won't have to discussed again in this bug?'''''''''''
Sure, here is my bug report:
https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/723820
..and this is a another one thats ben around since a time that some said
my bug was a duplicate of this one: (in this one it seems to be fixed with
11.04, but it still doesnt work for me)
The link to that one is:
https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/178442
..but as Ive said, it still doesnt work for me, maybee has something to do
with that ive have not added those lines they wrote about there:
## as below
<confdir:pcm/front.conf>
ICE1712.pcm.front.0 {
@args [ CARD ]
@args.CARD {
type string
}
type asym
playback.pcm {
type route
ttable.0.0 1
ttable.1.1 1
ttable.0.2 1
ttable.1.3 1
## end
Dont know what they do but maybee that has something to do with that I
have an 10 channel version of the ICE 1712 chipset and the drivers maybee
only configrated for maximum 4 channels and all you have to do is to
specify the following lines, aux5,aux6,aux7,aux8 and so on? and then it
maybee work? i dont know.

'''> ''For doing music on the computer you will want to use Jack instead
of Pulseaudio. With new enough Jack and Pulseaudio they should (I have no
personal experience) be able to cooperate so that when Jack starts,
Pulseaudio automatically releases the sound card, so hopefully you would
be able to easily use Pulseaudio for "normal" tasks and Jack when doing
music.'''''''''''
Aha! Then i understand a bit more how its built. But what are OSS drivers
exactly?
But plain Ubuntu that is installed by "default" (in other words, Not
Ubuntu studio that is installed) doesnt use Jack as far Ive understand?
Cant we get it to work using Pulseaudio?
If im correct, Pulseaudio and Alsa is the same, right?'''

>''Now I'm losing track of what you're doing. I thought you didn't get any
sound? But now you're saying that you get some sound, but with
glitches?''''''''''''''
Oh, sorry, my misstake in explaining correctly.
Firstly at plain install both ubuntu and ubuntu studio Ive got sound to
workright out of a new install, I think that was ubuntu version 9.10
maybee or 10.04 and but at some version it stopped worked, maybee it was
version 10.04 or 10.10, I dont remember wich was wich.
Note: as I remember it did work right out from the box with these versions
in ubuntu, BUT with glitches in the audio making it unusable, but it did
work. Then at some ubuntu version that stopped working so there was no
sound at all.
Then ive managed to install oss drivers and it did work, but Ive thought
that it shouldnt be necesarry to search for drivers to make it work from
the start so Ive contacted you guys.
As i can remember Ive got it to work with alsa at some point. I did search
and found a guide on how to do it but now I dont find that guide. But then
Ive managed to get it to work perfectly.
Now from fresh install in ubuntu 11.04 it dont work.
Now Ive tried on my own using this guide to make it work but Ive halted at
the point that it says that linux is waiting on the sound system to
respond when ive tried to go to configurations for sound.

>''You're right. But this is already taken care of - Pulseaudio will use 2
second buffers if the sound card driver is able to provide that big
buffers (otherwise the maximum is used). For giving good interactivity,
the buffer is rewritten when something happens that requires immediate
reaction (volume change, stream pause, stream creation and so
on).'''''''''''
Ok, that was smart with the rewriter feature.
'''
'''
>''I'm a bit confused because you said that you actually did get it to
work,
but anyway... my initial guess is that because the sound card is aimed at
professional audio work and not as an audio interface for entertainment
playback, the sound card driver doesn't provide any device identifiers
with known semantics (like "surround71").''''''''
Well, you could say that it is intended for professional audio work yes,
(but i would say in the starting range for professionals but thats another
discussion).
BUT
the Ice 1712 chipset is used in a lot of soundcards, even in M-audios
starting range of cards that is only a simple 2 channel soundcard, and
those cards are aimed both for the profession and for the consumer wanting
a little bit better audio quality. So both yes and no to that statement.
Actually, If people dont use the soundcards on the motherboards or one
from creative, then often the next alternative use to be from m-audio or
terratec and the likes. Next step ("the next level") is if you have money
or is a bit more experienced musican and then you dont buy an M-audio but
maybee one from Digidesign / Avid, Focusrite, RME and the likes.
So I think there are a lot of users using M-Audio cards since thats the
next level from creative to buy kind of..
'''
'''>''But guessing is a bad substitute for knowledge, so could you provide
the
Pulseaudio startup log at verbose logging level? The way to get the log is
the following:''''''''
Sure, but as Ive said before, now Ive tried to fix this on my own and
applied this "fix", but without result. It did work by using this fix in a
erlier version of ubuntu, unfortantly i dont remember wich version.
This is the link to the so called fix:
https://tango.0pointer.de/pipermail/pulseaudio-
discuss/2008-January/001240.html
That fix is getting mentioned and discussed here:
https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/178442
Maybee Ive should reinstall Pulseaudio and then provide the log as Ive
tried that fix mentioned earlier? that maybee would give you the detils
youre looking for.
