Hi list, I received a pair of brand new KEF X300A amplified speakers. It contains an USB DAC, so it should act as a generic soundcard, isn't it? Sadly, it seems to have an USB communication problem. Alsamixer and amixer are complaining about an "Invalid argument", caused by an EINVAL error returned by ioctl while trying to read from the device. Also, VLC complains about an "Input/output error" (alsa audio output error: cannot open ALSA device "default:CARD=Speaker": Input/output error) Please find my full alsa-info here: http://www.alsa-project.org/db/?f=2309053ada96a70e7b6205a599ef0e911b663cd5 I booted the last version of Mint Linux (as a live CD) and I have the exact same error, so I guess this is not related to a broken setup of my Arch box. It works flawlessly out of the box on Windows 7. I also reported my problem on the Arch BBS https://bbs.archlinux.org/viewtopic.php?id=158623 Thanks for your time, -- Benoît Zugmeyer ------------------------------------------------------------------------------ Everyone hates slow websites.
