Fixing wireless regulatory support (crda, wireless-regdb) on openSUSE Tumbleweed

On recent SUSE-based distributions such as openSUSE Tumbleweed (and potentially also 13.2), executing iw reg get to check your WiFi device’s regulatory setup will likely get you an output such as this:


global
country 00: DFS-UNSET
(2402 - 2472 @ 40), (N/A, 20), (N/A)
(2457 - 2482 @ 40), (N/A, 20), (N/A), NO-IR
(2474 - 2494 @ 20), (N/A, 20), (N/A), NO-OFDM, NO-IR

Correcting the soundcard order with onboard sound and HDMI output

Like many current devices with HDMI output, my Latitude E7450 offers multiple sound cards but configures the HDMI output as sound card 0 (the default). And xfce’s default sound mixer doesn’t offer switching the default output…

To correct the soundcard order, add this to your /etc/modprobe.d/50-sound.conf (valid for openSUSE 13.2, probably other distros as well):


options snd-hda-intel id=PCH index=0
options snd-hda-intel id=HDMI index=1
