After updating my system to Ubuntu Trusty Tahr (development branch) Release: 14.04 my soundcard VIA Technologies, Inc. VT8237A/VT8251 HDA Controller is not working anymore on the newer kernel (3.12). After booting an older kernel (3.2) the card is working. Already tried various options in /etc/modprobe.d/alsa-base.conf, e.g. options snd-hda-intel probe_mask=1 model=3stack-dig but without success Configuration infos lspci: 04:01.0 Audio device: VIA Technologies, Inc.
