I'm getting ready to buy a Sony VAIO VGN-NW330F/S laptop with an Intel
GMA 4500MHD graphics chipset. I know many people have reported that the
closed nVidia driver has at times been hell on realtime kernels.
Is the Xorg driver for this recent Intel graphics chipset known to be a
problem in any similar way to what has been seen with the nVidia driver?
I have heard that Intel's recent integrated graphics chipsets are
starting to have better graphics performance than before back when they
were just for a functional display and not much more, but also I'd like
it to behave with audio too.
Or any thoughs on recent Sony laptops for Linux in general?

Folks,
I'm an audio lover that prefers smaller speakers in smaller spaces and i
don't need/want 5-8 speakers in my listening space. I have found that i
prefer the effect of vocals/sound effects that are mixed in center in
stereo speakers, over a center channel. It sounds more natural and
rounded to me.
I would think that the same thing could be done in the rear speakers of
course and also front to back by adjusting the front-back balance of
sounds.
Couldn't one create the sound of a fly moving through out a room simply
by adjusting the balance of 4 speakers?
If so why do we need more than 4 speakers?
I have an audio system for which i'd like to set up 4 channels. I have 2
Anthony Gallo Acoustic Reference 3.1s and would like to swap them out
for 4 Stradas and 4 subs (with some extra money of course).
If i do that and play back a 5.1 or 7.1 movie soundtrack or music disc
what am i going to not have vs a full 5 or 7 channel set up?
Will things down-mix properly (using pulse audio for reference)?

This is complicated. The various options are
discussed at:

and:
http://www.ambisonia.com/wiki/index.php/Bass_management#What_to_do_with_the…
Ignoring the LFE-channel is not recommended
as it may contain stuff not present elsewhere.
Adding it to W is good, but it will then end up
in the main speakers and these may explode.
(The solution to this is to incorporate a limiter.)
You could also carry it forward as a separate
channel and feed it only to the subwoofer at
the end.
Regards,
Martin

I have always wondered what the wee slider
thing was for. Now I know. That was the most
useful post I have read in years.
Many years ago I used the nozzle on a vacuum
cleaner to repair a tweeter on a Monitor Audio
speaker. Although it worked, the final result
didn't look very pretty. I would therefore
suggest trying the cardboard tube first.

Okay, I found two bugs in the EHCI driver that explain all your
problems. Apparently, these bugs show up only if the USB host
controller issues interrupts not for every completed microframe; you
seem to be the only one with such hardware.
I've CC'd you on the patches; holler if you need entire files.

A few years ago I used to use my gnx4's usb interface to capture the audio
from the pedal. at some point before 2.6.20, I don't remember the kernel the
regression originally happened in, It stopped "just working", and only a usb
device was detected, but it wasn't accessable to use, and now is no longer
recognized as even being plugged in. I'm trying to figure out if my hardware
is now bad, or if other people noticed this behavior, and I should dig into
it some more.

Multiple surround speakers fed with the same
signal is what you hear in a cinema.
Recreating that would therefore seem to be a
useful path to go down.

All,
One of the M-Audio 4x4 tweeters unfortunately got a bump in it. It
now makes a terrible sound on some frequencies. Anyone has ever
replaced one of these ? Is it possible to get a replacement from
M-Audio ?
Thanks for any suggestions/ideas (apart from buying a new pair of
speakers !)
