Hi,
USB-Audio.conf contains:
# DO NO EDIT; this is an internal ALSA file. # If you want to add your own definitions, put them into /etc/asound.conf or # ~/.asoundrc, with "cards." before the "USB-Audio", e.g.: # # cards.USB-Audio.pcm.use_dmix."NoiseBlaster 3000" no # # If your device requires such a definition to work correctly, please report it # to alsa-devel@alsa-project.org.
However, snd_config_hook_load_for_all_cards() will completely skip loading of /usr/share/alsa/cards/USB-Audio.conf if one has existing configuration elements in cards.USB-Audio.
I was just hit with this while debugging an issue with a user. Should users just edit /usr/share/alsa/cards/USB-Audio.conf directly until such entries are added upstream, or should this be somehow fixed in alsa-lib to work as instructed?
