My bad; I'm still new to this. Hopefully this one's formatted correctly.

+ * The MSI GE66 Raider 11UE drives its speakers through a Realtek ALC1316 smart

+ * quiet and takes about 0.4 s to reopen, so the start of every sound that
+ * follows a pause is lost. Headphones do not pass through the amplifier and are

+ *

+ * carries the 16-bit register, 0x24 and 0x25 the value's high and low halves,
+ * and 0x26 commits. Bit 4 of the commit word is a self-clearing go bit.
