It is extremely unlike that your embedded device has separate chips to decode the HDMI sound signal and then convert it to analog, when the same is already available with the normal HDA device. Your alsa-info output shows that there is an ALC262 codec connected to the "SB" device; this chip wouldn't have been put there if it didn't have a function. Try unmuting and raising both the Master and Beep controls. The Windows mixer elements are software-emulated and shown for all devices. (I don't know why the only working device is labeled "HDMI", maybe someone just mixed up the HDA devices.) Regards, Clemens
