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?
I cannot figure out how to automatically set
permissions of
/proc/asound/card1/pcm0p/oss. I tried Having the line
options snd major=116 cards_limit=4 device_mode=0660
in /etc/modutils/alsa, but alsa won't come up, saying: "Unknown symbol
device_mode".
This is only for device nodes in /dev/, if devfs is enabled. 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).
