I recently tested a Soundblaster Extigy on my Mission One running LibreElec 9.02 x86_64 . I was so impressed with the sound quality difference that I want to keep the configuration, however running one USB port short now.
So I figured I could eliminate the USB IR receiver (MCE USB that seems to have been auto detected).
The only problem is I have no idea how to activate the correct LIRC driver in LibreELEC
The following pages seem helpful as they mention the same hardware but it apparently does not apply to Libreelec
I also confirmed /proc/asound/cards shows (much like in the page above)
0 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xd0810000 irq 95
1 [Extigy ]: USB-Audio - Sound Blaster Extigy
Creative Technology Ltd. Sound Blaster Extigy at usb-0000:00:14.0-4, full speed
Any help appreciated.
