I just thought, that maybe you should check out.
Thanks qzem, but FYI, I think I've already read just about every FM and BT thread on devices with the TI chips by now, on XDA and elsewhere. (Well every useful one anyway.) Also several threads on devices with Broadcom chips, since those may offer clues to HTC and other manufacturers audio routing. Any device with a 7227 or similar chip may be similar in audio issues. That includes lots of newish budget and mid-range devices including the LG Chic (and LG Optimus One) I tried a few weeks ago.
I've managed to download the latest TI code for their testing utility "fmradio", and other stuff, so I'm not wanting for code right now. I just need to take the time to pore through it and experiment.
My "pre-alpha" level App Inventor app is working nicely now, so I'm ready to move back to solving the audio routing issues. Since the HTC Legend stock FM app works, (it has one right ? I never tried or even looked hard before rooting and CMing), we know the hardware works. And I'm absolutely positive that sooner or later, either I or someone else will solve the routing issue.
Perhaps within the next week or so I'll have an app ready for anyone who wants to test (Audio or no). As is, it might even output sound on some devices.
As for the Motorola Droid (original aka Droid 1), that's the one that after so much work by some people, it was found that the FM antenna connection went nowhere. The connection point was under an RF shield so would require impractical major surgery to connect. The threads I've read indicate much despair when this was discovered.
We Legend owners will not suffer such a fate given that the stock ROM supports the radio fine. (Right?) I'm still not sure yet if the Legend has a decent Tx connection for the transmitter. If not, the Tx may only have a few inches range (which will work for some people), or even none at all.
