In Linux, you can try this:
grep 'at EC' /proc/asound/cards
Sample output:
ThinkPad Console Audio Control at EC reg 0x30, fw 7WHT19WW-3.6
7WHT19WW is the version in different notation, use search engine to find out regular version - in this case it's a 1.06 for x200 tablet
Alternatively, if dmidecode is available, run the following command (as root) to
find the currently flashed BIOS version:
dmidecode -s bios-version
On a T400 running the latest BIOS this would give 7UET94WW (3.24 ) as result.
