2nd week on Arch.

Problem: ALSA: no sound for mplayer, ogg123, flash. Skype however could playback.

Solution: wrong selection of default sound device during boot

Set a) default snd card and b) order for sound cards in:

$ cat /etc/modprobe.d/alsa-base.conf
options snd slots=snd_hda_intel,snd_usb_audio
options snd_hda_intel index=0
options snd_usb_audio index=1

Then reboot.

How to detect the cards:

$ lsmod | grep '^snd'

Problem: truecrypt could not create a file container ("failed to set up loop  device" after formatting).

Solutions:

1) Activate loop module with

$ modprobe loop

2) or on boot by putting it in:

# echo "loop" >> /etc/modules-load.d/truecrypt.conf

Installed: openssl, openvpn
