A long time bug in recent kernels: Mixer settings have not been saved/restored
and everything comes up very silent.
I looked at the script. There are two functions in it to do this. They go
through all the motions except .... there are no actual calls to alsamixer or
anything like it. In other words, nothing doing.
What two calls should I put in here to get the mixer setting saved and
restored?
greetings!
i am installing gentoo on an hp zd-7140us laptop (with nVidia GeForce FX
Go5200 video), using the mm-sources kernel (2.6.10-rc1 with andrew
morton's patches), but am finding that neither the gentoo ebuild of the
Nvidia driver (nvidia-glx), nor the linux driver distributed by nVidia
(v 1.0-6111) is compatible with that kernel.
has anyone here successfully used nVidia under this kernel? if so, i
would be delighted to have some details.
failing that, is there some collective wisdom …
[View More]out there about how to
construct another kernel (preferably 2.6), patched for low-lat etc,
which IS compatible with the nVidia drivers?
many thanks in advance.

Just out of curiosity: just what makes something ASIO compliant? Is it mearly a spec that has to be met or is there more to it than that? I've never really been able to find anything about just what ASIO is. It has seemed to be more of a buzz word used in the marketing of PC/MAC sound …
[View More]hardware than anything else. JACK used to have ASIO mode didn't it? Was it just a pointless option that was dropped?

I've been connecting my Sound Blaster Live card
to an old Fostex X-26 Multirack tape deck. I don't
record to the tape deck, just use it as a small amplifier
and run the guitar signal through it and into the
sound card.
This means I have to use a Radio Shack Y adapter,
( 1/8 inch sterio plug to two phono plugs) to connect
the sound card to the tape deck.
This works but its awkward. I was wonder what
setups other people use to get a signal into their
sound card. Maybe I could improve on this, …
[View More]without
spending too much money. Are there any small, clean
signal amps out there that allow you shut off the speaker
and have an audio line-out?
Any information would be welcome.

Finally, I created a WAV file that plays back!
I think the problem was:
1) I had not checked the little "rec" box under "line-in"
on the Gnome sound mixer ( or volume controller ).
2) I think there was a problem with impedence matching between
the sound card and the device I used to interface with it.
The adapters and chords I used to hook the two devices
( sound card to guitar amp or sound card to audio mixer)
were all good and the devices themselves worked fine,
as …
[View More]well as the sound card. Otherwise, why all I got was
an empty file that played nothing is still a mystery to me.
I finally got a usable WAV file by interfacing the sound card
with my ancient Fostex X-26 Multitrack tape recorder and using
its two audio line-out ( Left and Right) to plug into the Sound Blaster
Line's blue one-eight inch line-in using a Radio Shack adapter.
On the computer, in Gnome, I checked the little "rec" box next
to the line-in on the mixer, set the proper switches for volume
(Volume, PCM, IGain, Line-In, etc ), started a terminal, and used the
command: rec -v -r44100 -c2 -s -w input_file.wav
I did not record to tape. All I did was use the tape machine as
a small amplifier and ran the signal through it.
guitar->X-26 tape deck-> line-out ( audio plugs) ->
Radio Shack adapter -> one-eight inch blue line-in Sound Blaster Live
Then I had a lot of fun doing the Sox examples using the
input_file.wav. This is great!

1. OK. I took out the numerical argument. It either defaults to 0 or does not
need it to store/restore everyting.
2. The restore script had:
if msg("alsactl restore ....."); then ...
I changed that to:
if alsactl restore .…
[View More]...; then
This works.
So from where came the 2 and why the msg() function?

Didn't work.

So .. they are there. These take a numerical argument and would be repeated
for each numbered audio card. Mine had argument 2 which corresponded to an
mpu401 interface. Hardly audio. The one supported audio card is card 0
according to /proc/…
[View More]asound/cards. So I changed it--see what happens.
How did the 2 get there?

I built and installed the lsm kernel ontop of T3, but …
[View More]on boot I get
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
Could this be security not having permission to access the disk?
2.6.9-rc3-mm3-VP-T3 works fine?
Is there some way to tell where the kernel is getting stuck?
