[HOW-TO] Downmix stereo to mono and boost volume for the internal Nook Color speaker!

[roberto]

The first script will give mono with boosted volume and the second one give stereo with boosted volume.

So the boosted volume one will return it back to stereo? Or do I need to create the first script outlined in post 1?

The boosted volume returns it to stock with just the volume increased. The internal speaker reverts to mono and when a jack is plugged in, it will run in stereo in the speakers or headphones but a bit louder.

As it stands now, I might clean up and re-do the main post. I love to explain what I found, what to do and even further, try to explain what is going on in anything I ever post anywhere for those that are curious and might want to change or improve on things. Unfortunately I tend to run on and on and sometimes it makes my posts a little confusing overall...... even for me.

With that being said, the initial post on how to do this could be as simple as download the two files (plus I should post a copy of the default one), copy everything to your SD card, mount system as rw using Root explorer and then copy to /system/etc/ using root explorer.
To switch I could just post the three .sh files for use in gscript and a quick how to add them to and use gscript.

If I can get the updater-script to work with an update.zip style installer, it will certainly make the how to very simple for everyone.
I might get some time later to try that.:-\

Hi all, first post here and very new to android in general.
I don't actually have an asound.conf in system/etc so I figured I would attempt to copy the downmixed and boosted file over to the directory. I tried to use ES file manager with superuser permissions, but kept getting denied. I don't have adb installed and am kind of reluctant to mess around with the android sdk at the moment.

I am wondering if there is a way to copy those files there using gscript from the sd card? Or if there is some other simple way to get the 2 files from the SD card to the correct folder on the nook?

Thanks

The nook speaker already does l/r mixing to the mono speaker through hardware. All you really need to do is boost the output.... and that can be done with any decent free EQ app. I use this one:

Just raise all the bands to +10db or whatever you want. 10db will clip the speaker when you have the volume rocker all the way up, but its there for when you need it on quieter videos/mp3s/etc.

The nook speaker already does l/r mixing to the mono speaker through hardware.

Everything I've read and my own testing (playing with L&R output on Mobo Player) tells me that this is incorrect. I wish it were correct, but it doesn't seem to be the case.

I had trouble that way also also, but figured out that I could upload the file using Dropbox. I did that and moved it to /system/etc/ with the correct permissions, using Root Explorer. The sound seems to be working fine, but it's hard to tell much difference (it is at least as loud as before, in any case). I'll try it with earplugs later and see if I can tell a difference. I am deaf in one ear, which is why this mod appealed to me).

Could someone please tell me the correct permissions using root explorer for this please? I had it working fine with Cm7.0.2, but once I upgraded to 7.0.3 I couldn't get it to work. Any insight would be greatly appreciated.

Nook Tweaks in the market fixes this, as well gives you a slider to control pre-gain for both external and headphone out. Works great.
