Comment 9 for bug 890346

Can we clarify what the issue is in this bug?

Currently, record is indeed broken on one channel, one channel will record like untuned FM hiss, the other channel will record correctly though IF your input mixer settings are correct (see next paragraph). We're working on solving that (it's an inherited breakage from vanilla).

Also, 4460 and 4430 Panda hardware have the Line-in jack physically wired to different inputs on the twl6040. For 4430 Panda it goes to Headset mic and on 4460 Panda, FM analogue input. So, you need to adapt your mixer settings accordingly.

To help with that, I have added a patch that changes the name of the Alsa 'card' for the onboard sound device, for 4430 Panda it's "Panda" and for 4460 Panda it's "PandaES". You can use this to choose the correct mixer settings.

As I wrote a while back above, mixer names have changed in upstream kernel, you will also need to adapt them or your mixer settings won't be correct for playback.

On current tilt-android-tracking, on ICS, both onboard and HDMI audio output is workable at kernel.
