Are you talking about speaker volume or headset volume? Volume+ on the Market will increase speaker volume, but you must be running Gingerbread (the API it uses doesn't exist in Froyo). And Voodoo Sound can increase your headset volume, but you do need a custom kernel that has it built in to use the Voodoo Sound app from the Market.
what's a custom kernel? See what I mean?
Not ENTIRELY true. The FREE voodoo requires a kernel with the driver embedded in it. The PAID works just fine 100% stock I will say voodoo rules for headset, especially if you use it wired up to a home/car stereo. The audio hardware is second to none.
According to the market description, I need to be rooted for the app to work.
LOL.. Sorry Ted, it was not intended to come off that way... I've been around here with you long enough and I've read and understand your concerns about rooting. I don't have a problem with your choice to run stock.nice sales pitch Paul, like saying that Ferrari's are not for everyone.
Okay. Post root (sound of crowds cheering) I wanted to report on my initial foray into volume enhancement. Volume+ 1.7.3 is available in the market but if you register at the website, you can have it for free. Problem is, you can have it. Initial boost is clean but lacking in bass. If you boost a little bass, sound gets muddy. But mostly, whether playing songs from SD card or streaming, if you multitask, you will be rewarded with glitchy cut outs. Very annoying. Any feedback on Voodoo would be welcome before I spring $4 for it. Thanks for reading.
