Somebody in the thread at some point said:

| Good, no top on my phone either.

| Great I will try that tonight then.
I set alsa with a similar config from here
alsactl -f /etc/play_wav_speaker.state restore
and I can get a delayed click / pop from the sounder at the back about
3/4s after resume. There's no sound on suspend. I tried forcing
CODEC_3V3 for the codec analogue side to stay up in suspend, but it did
not remove the click / pop.
The physical amplifier is hooked to the earphones + earpiece in GTA02,
not to the sounder, so the amp controls are nothing to do with it.
I suspect maybe during the long spew of I2C register dumping that is
happening after resume now, that we arrive at a state in the register
set temporarily that sets wrong routing to drive LOUT2/ROUT2 that is
hooked to the sounder. I'll meddle some more with it tomorrow.
