You may have missed these tidbits... -- It seems the file "/proc/asound/card0/oss_mixer" is the magic... https://github.com/opensrc/alsa/blob/master/Mapping_oss_mixer_controls_to_alsa_mixer.md Also, look at: https://wiki.debian.org/DebianEeePC/HowTo/Sound#ALSA_OSS -- So it seems in a "/mnt/kd/rc.local" (chmod 755) file looking something like: -- #!/bin/sh if [ -f /proc/asound/card0/oss_mixer ]; then echo "ALSA_OSS, setting oss_mixer..." echo 'VOLUME "PCM" 0' > /proc/asound/card0/oss_mixer echo 'LINE "LineOut" 0' > /proc/asound/card0/oss_mixer echo 'MIC "Capture" 0' > /proc/asound/card0/oss_mixer echo 'PHONEIN "Digital" 0' > /proc/asound/card0/oss_mixer fi -- as per the example above, though the argument pairs may differ for your hardware, that may take some googling and trial and error.
