Ugh... sometimes i hate the back button on the mouse... just deleted everything I typed when I pressed it by accident. anyway... I had 2 things to say...
1) the VC baseband is garbage. I had all kinds of problems using it with CM7, might be why spring pulled that update, who knows... I don't feel like re-typing the details, but if enough people ask I suppose later I can share my bad experiences - in a nutshell... the phone no longer worked as a phone...
2) I found a work-around to getting perfect sound for music through the headphones... but, it does require a piece of hardware (or the latest build fixed the audio and I just discovered this for nothing/it means nothing)
Anyway... for the fix... use a 4-connection headphone jack. I have headphones with a mic (headphones with mic are 4-connection jacks) or use an adaptor. Perfect sound with that. Want to save some money with that still? There's another option similar that would let you get perfect sound when plugging into your car stereo or just a set of speakers... if you plug in a 4-connection jack, then quickly switch it to a normal 3-connection jack (regular jack or headphones), it still thinks it's a 4-connection or something (audio still works right). Since these are analog plugs, this should even work with just a plug that isn't connected to anything - so maybe you could buy a 4-connection jack as if you're going to use it to make a cable and save some money. This at least works for me so far. Hope it does for others too.
BTW, if anyone knows where I can buy an adapter at a good price for my car, i'd appreciate that. I'd prefer 1 with a mic build in to the adapter so I can just plug the car stereo in and not worry about anything. (and yes, i know the mic may not work at CM7's current state).
