You can enforce that a sound card becomes alsa hw:0 and nothing else is required, since the sound servers use alsa. Write a /etc/modprobe.d/alsa-base.conf with options snd slots=driver_name for example $ cat /etc/modprobe.d/alsa-base.conf # ALSA module ordering options snd slots=snd_hdspm,snd_ice1712,snd_ice1712 I just noticed, that on my machine the do-release-upgrade must have removed some very important configs, seemingly /etc/modprobe.d/alsa-base.conf, too. -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
