GMusicbrowser and Simultaneous ALSA Output for two audio device

I have one USB and one Onboard sound device. Using GMusicplayer for playing music through the USB with ALSA output:

Since I can not add (or I don't know how to add) the other device on GMusicbrowser ALSA device settings I tried this solution but it is about pulseaudio and I don't want to use pulseaudio for my USB device.

I want to use ALSA for GMusicbrowser pass to the USB device and whatever that is playing by GMusicbrowser pass to the onboard device (with pulseaudio or ALSA).

aplay -l result:
