https://bbs.archlinux.org – Hi !First of all, I'm new to this forum so, if I made a mistake about posting in the wrong section, I'm sorry.I've a strange problem on my netbook with alsa. It's a fresh arch x86_64 installation. Udev detects my sound card. I can see it in /proc/asound/cards% cat /proc/asound/cards 0 [Intel]: HDA-Intel - HDA Intel HDA Intel at 0xf7cf8000 irq 45But when I enter for example aplay -l that shows me that no cards was found% aplay -l aplay: device_list:256: aucune carte son n'a été trouvée...I can also see that snd-hda-intel was loaded with lsmod.
