NV Soundstorm support? / Recording broke!

NV Soundstorm support? / Recording broke!

[Daniel MacDonald]

Hello ALSA devs!

My biggest question is- what is going on with Linux
support for NVIDIA's NFORCE 2/ Soundstorm chipset?
Have NVIDIA been contributing code or patches to ALSA
or has the ALSA driver been created independently?
More importantly, how long before we see PROPER
support for the soundstorm under ALSA, instead of just
a hacked intel8x0 driver? I want multiple dsp channels
and 24-bit audio I/O under Linux please NVIDIA!

I've been thinking of starting a petition as I'm sick
of waiting for this. They release new Linux drivers
for their GFX cards every other week so why can't (at
least temporarily) devote some of their Linux
workforce into getting Soundstorm support under ALSA
sorted?

The main reason for my building impatience is as Mr.
PBD said that he's have that long, long, LONG awaited
Ardour rc out by now- what happened Paul? We expect
release candidates to have bugs- as long as it
compiles under the major distros that'll be enough.
Bring forth that glorious tarball pleeze!

Anyway, I have installed ALSA 0.9.4 on Redhat 9 XFS
and although sound output works fine, recording (both
line in and mic) doesn't want to work at all (under
Audacity CVS, but I tried it with the GNOME sound
recorder too). I did get recording to work on this
same machine but when I was running Mandrake 9.1 and
ALSA 0.9.3. Has anybody else reported/ solved this
problem?

I tried downloading the latest alsa-driver CVS but for
some reason it refused to download past the patches
bit and it was complaining about some ALSAKERNEL stuff
so I just gave up with that.

Hopefully somebody will be able to answer at least
part of this multi-faceted whine-fest of a mail.

Thanks v. much!

The beta is being tested now and when that is ready the rc will probably 
be released.

Never seen it but you should try using alsamixer and arecord/aplay. 
There is a howto via the quicktoots project at the LAU guide (see below).

The tarballs are working AFAIK. Did you use the ones from alsa-project.org?

i never saw the original for this, but anyway ...

last week, there were 5 "private" releases of a tarball, most of which
have been used to resolve issues relating to the build+install
process. there is one "showstopper" issue that doesn't affect
compilation but does dramatically effect usability for many people. i
am currently deciding whether or not to ignore this and put 1.0beta1
on sf.net, or to fix it before that first "public" beta.

there is no technical contact with nVidia at all.
the necessary information was taken from their driver.

it's interesting whether these features are really supported on this
chipset :)

because they don't give any technical information.
hopefully the situation will be better in near future...


ciao,

Takashi

I'm almost positive that the Soundstorm is only a 16bit/48khz part. I'm also pretty sure that nvidia never advertised the soundstorm as such.

The soundstorm is generally attached to a Realtek ALC-650 for A/D-D/A functions. From the Realtek specs (http://www.realtek.com.tw/products/products1-2.aspx?modelid=30) it has a 20bit DAC but only >90dB S/N.

Looking at the nvidia specs (http://www.nvidia.com/docs/lo/2027/SUPP/APU_TechBrief_71502.pdf), it looks like one might be able to do 24bit, but it looks like you'll only get 48khz. Still, because they don't really mention it, I doubt you'll get anything more than 16/48 ..

later,
Steve
