Multihead dual gpu setup

Hello ,
I installed Arch Linux and gnome DE on my old dual gpu (ATI & Intel) laptop and followed ArchWiki to setup Multihead for ATI gpu https://wiki.archlinux.org/index.php/AT … head_setup everything went good and smoothly after creating 20-radeon.conf file and booting Arch Linux with the Kernel parameter radeon.audio=0 I ended up with a working external monitor via HDMI with no HDMI audio output and the internal monitor is not working and is not turned off just stuck with few info lines I usually see when booting Arch Linux,
how to get both monitors working I mean clone or mirror the laptop screen to the external monitor?
is there any way to get audio output from the external monitor?

lspci output is:

$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02)
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Robson CE [Radeon HD 6370M/7370M]
 

$ lspci | grep HDMI
01:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Cedar HDMI Audio [Radeon HD 5400/6300/7300 Series]

xrandr output is:
