I have kernel 2.6.18.1. I recently upgraded alsa both in the kernel and
userland to 1.0.13.

Running btsco and kernel module without a recompile causes this:
kernel: EIP: [<f992054c>] snd_card_bt_sco_playback_open+0xac/0x110
[snd_bt_sco] SS:ESP 0068:d3d01e40

Solution was to recompile btsco and snd-bt-sco module.

However, now no sound issues from the headset and no microphone is
picked up.

aplay -B 1000000 -D plughw:2 podbay.wav completes but nothing comes out
of the headphones.

hcitool info for the headphone is:

This worked previously before the alsa upgrade (required to fix a
problem with a soundcard).
