Re: Auto mute mode

[David Henningsson <david.henningsson@canonical.com>]

Hi Hui,

I need to take care of a sick child today so I can't work.

The bug Kailang is talking about is https://bugs.launchpad.net/bugs/1535533

And he keeps talking about auto-mute mode, and I've tried to explain to 
him more than once that if muting the amp-out on node 0x14 does not 
cause the speaker to mute, then that's the real issue here. And that 
seems to be the case, but I can't double check because I don't have the 
hardware.

I don't understand Kailang's answers, because his English is too bad and 
contain very few words. Maybe you can talk to him in Chinese and getter 
better answers?

Thanks in advance,
   // David
