Nothing is done to the speakers....speakers are at default....no dampening involved. Learnt my lesson after burting one....however sound quality should be increased indirectly.

Thanks alot for the awsome script Savage

I usually plug my n900 into my cars sound system with a little AUX cable. The cable from the manufacturer is around $120 because it has an amp but I got a standard cable for $12and use that.

It is still better than the FM radio transmitter as it suffers from a lot of interference regardless of the station used even with FM Boost.

Only problem is that I have to have the n900 on full volume and the cars volume high, alot of sound quality is lost. Would it be possible to boost the n900 output further?

I got this explanation from the cars actual forum site when someone asked the same question about their iPod.

iPods have a low level output signal - around 300mV - (as they use the headphone jack rather than a dedicated Line Out jack) and require the amplified cable (the one in the eBay pic is not amplified - amplified leads have a small shrink wrapped cylinder - which contains the amp - in the middle of the cable). If you do not use an amplified cable with an iPod, you need to turn up the iPod output to near max (leading to output signal distortion) and the Ford ICC volume control right up (leading to alternator whine being heard).

An iPod connected via the Ford amplified cable sounds really good. An iPod on an unamplified cable does not in comparison.

Other MP3 players put out 850mV to 1v (closer to a Line Out spec) and hence will work quite well on an unamplified cable. Check your MP3 player specs to see if it says what the output signal level is as an unamplified lead may work fine with your MP3 player (whereas an iPod will always work best only on an amplified cable).

Can we reinstall swappolube after this patch and use it?

Is there any documentation for all those *.parameters files and their attributes somewhere? I'm curious what can be get from them. Also according to Savage experimenting might end badly, so it could save few devices.

I think the CPU usage is ok if you are listening music or calling. But, if you are talking about CPU usage without playing anything, them we have a problem.

Also, I have a question: I have installed kernel-power to overclock and to install the modules iptable and iproute. Do I need kernel-power to load those modules? I don't want to uninstall kernel-power. BTW. how can I uninstall kernel-power?

Thank you in advance for reading and downloading.

can you start a new thread regarding your patch? not cool to thread steal

Hmmm, there isn't anything much that I could do about the fm transmitter except enabling the stereo widening.

Also It' not safe to install swappolube after using the BoostN900, you would have to remove it first with the RemoveBoostN900.sh script.

About documention regarding the.parameters file I just briefly list out what I know they each relate to:

bta2dp.parameters - bluetooth headsets (when using stereo output)

btmono-hfp.parameters - bluetooth headsets (of some type)

btmono-hsp.parameters - bluetooth headsets (of some other type)

hp.parameters - earphone (phone calls)

ihf.parameters - speakers

ihfandfmtx.parameters - fm transmitter

fmtx.parameters - fm transmitter (probably used for applications other than the default media player to access)

hs.parameters - headsets (of some type)

ihfandheadset.parameters - headsets (of some other type)

ihfandlineout.parameters - audio jacks (for some type)

lineout.parameters - audio jacks (for some other other type)

ihfandtv-out.parameters - tv out audio (for default nokia n900 tv cable)

tvout.parameters - tv out (probably for cables not manufactured by nokia)

About cpu usage when using stereo widening, the cpu usage won't fly up unless the particular component you enabled it on is being used.

for example if I enable stereo widening on ihfandheadet.parameters (the headsets), whenever the audio i being played through the headsets...only then would it increase cpu usage. If headsets are not in use, the cpu won't go up.
