Re: KX3 firmware issue?

[Drew Arnett]

Hi Dave,

Any news on the audio manual & remote control issue?

I found that the mailing list wasn't that helpful for technical
issues.  I found a FW issue, which took some time to get confirmed.
(WIll it get fixed?)  Someone else reported a possible FW issue not
long ago, so I reproduced it to help them rule out HW.  (Will it get
fixed?)

I saw your report of a FW issue and thought I'd check with you to see
if there was any progress or if you would still like someone to
reproduce to confirm that it is a FW and not HW issue?

Best regards,

Drew Arnett
