But why does alsa complain about "Unknown symbol device_mode" then? A bug (in the kernel or alsa)? Or is this wrong in my .config: [atte@aarhus linux]$ grep -i dev .config | grep -i fs CONFIG_USB_DEVICEFS=y # CONFIG_DEVFS_FS is not set # CONFIG_DEVPTS_FS_XATTR is not set If I get alsa to recognize the device_mode=0660 (for instance by changing my potentially wrong kernel .config), where would the oss-emulation of my card that is now at /proc/asound/card1/pcm0p/oss show up in /dev? And are one of the devices (/proc/... or /dev) better in terms of a) stability b) latency c) supportedness d) something else or are they equal? >>Is there a new way of setting the permissions of >>/proc/asound/card1/pcm0p/oss or /proc in general??? > There is no way, except changing ALSA's source code. > The permissions of pcmxx/oss are set in the snd_pcm_oss_proc_init() > function in alsa-kernel/core/oss/pcm_oss.c (entry->mode). Bwadr. Don't wanna mess with that :-) -- peace, love & harmony Atte http://www.atte.dk
