NookColor Audio Input

---

Hi,
I'm trying to find a solution for my nook to get audio input working.
So far I have a BT headset that I'm able to pair.
The problem appears when I'm trying to use it as a microphone. The nook basically freezes.

I'm a dev, though not specialized in Android development.
What I was able to investigate so far is that Nook rom uses alsa and it dies somewhere when trying to get the hwId of my headset.

There were some theories saying that Nook rom builds do not have audio codecs for capturing audio inputs.

Any help/hints would be much appreciated.
Maybe we can get our Nooks a mic so our relatives can call us.
Thanks.

I would like to help but i am no dev maybe fat tire could do it or better drivers could be in ics try that rom i think it has blue tooth (you have to download the source on the second post and compile it for the most update rom if you didnt know)

Well, last time I give ICS a try, there was no sound at all.
So I don't know what to say...

Sound

Oh fattire said he was going to try to fix it.
I have no computer and cant compile from source so didnt know if he did or not

Update: I dont know if your using tyhe right nightly but some had usb host mode that you need to enable and there is an entire thread for blue tooth problems.

This is a question, so in the future I would put it in the Q and A section.
The nook color has no drivers for audio input, neither does the OS that the nook color uses. I have done a fair amount of research and asked myself, it simply isn't possible, trust me.

Well maybe drivers could be taken from the nook tablets os since it has a built in mic

But the Nook Color does not have a built in mic. What would those drivers be "driving"?

I imagine he is talking about if he connected it to a bluetooth headset.. I've always believed it should be possible since it has bluetooth, but the feedback I've gotten made me doubt it. Since the OP is a developer of some kind, if he wanted it bad enough maybe he could figure something out, I'm sure there are others out there who'd appreciate it.

mics

Exactly a blue tooth headset and so with cm 9 sound up the nook should already have a lot of drivers in it so it might work since it is open source why cant someone develop the software if it isnt already there

fat tire got sound fixed as you probably know so you might try again
