Re: [gentoo-user] Can't get ALSA OSS Emulation to work

[Nick Rout]

The setup on gentoo changed sometime around alsa-lib 1.09.

Leave ALL of the oss stuff out of the module config files (running
alsaconfig will set it up correctly)

Then set ENABLE_OSS_EMUL="yes" in /etc/conf.d/alsasound

my /etc/modules.d/alsa now reads:

nick@sf /etc/conf.d $ cat /etc/modules.d/alsa
# --- BEGIN: Generated by ALSACONF, do not edit. ---
# --- ALSACONF version 1.0.9a ---
options snd  device_mode=0666
alias snd-card-0 snd-via82xx
alias sound-slot-0 snd-via82xx
# --- END: Generated by ALSACONF, do not edit. ---

/etc/conf.d/alsasound now reads:

# ENABLE_OSS_EMUL:
# Do you want to enable in-kernel oss emulation?
# no - Do not load oss emul drivers
# yes - Load oss emul drivers if they're found

ENABLE_OSS_EMUL="yes"

# RESTORE_ON_START:
# Do you want to restore your mixer settings?  If not, your cards will be
# muted.
# no - Do not restore state
# yes - Restore state

RESTORE_ON_START="yes"

# SAVE_ON_STOP:
# Do you want to save changes made to your mixer volumes when alsasound
# stops?
# no - Do not save state
# yes - Save state

SAVE_ON_STOP="yes"
