ThinkBook G13/G13s G4 IAP and similar microphones not working recently

Nicht kategorisiert

I just experienced a strange behaviour with the named ThinkBook’s, that affects G13 G4 books and similar devices. After an upgrade of “Elevoc AudioProcessingObject” to (in my case) 4.0.5.199 via Windows Update, the microphone just stopped working.

After finding a thread on reddit about this, I installed the latest 5.0.5.238, which also did not work. Scrolling through the thread revealed that a user had this exact problem even with the latest 5.0.5.238 version. Installing 5.0.5.234 manually via device manager fixed the problem immediately, even without a restart.

Shows the available packages as .cab. They can be extracted manually and then installed via the device manager. Downgrade works by uninstalling or downgrading to a previous version, then rolling forward as much as needed.

cryptsetup “No key available with this passphrase.” even though you are 100% certain its the right key (Debian Buster)

Something I stumbled upon today. I tried to unlock a LUKS container and was 100% certain that the passphrase is correct. Still, cryptsetup would not unlock the container:

# cryptsetup luksOpen /container_file container
Enter passphrase for /container_file: 
No key available with this passphrase.

Digging around, references can be found to either a problem with the character encoding of the shell or to a bug with cryptsetup and Samsung EVO SSDs with certain older 5.1 kernels. None of these were the case.

After some trial and error, I upgraded the cryptsetup packages from 2:2.1.0-5+deb10u2 (from buster/main repo) to 2:2.3.5-1~bpo10+1 (buster-backports/main repo). Suddenly the container would unlock.

I think most of the time people either get their passphrase wrong or their header was corrupted somehow, but in this case: Some bug in cryptsetup. (Not reported yet, no existing report found yet.)
