My card works quite well, modulo the mic > problem and a lower output than in Vista, and I'd love to see it solved. FWIW, I'm seeing this problem as well (ALC268 too) on my Acer Aspire 5720Z laptop. Dupes of this bug report are NOT hard to find: https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3609 https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3637 https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3897 (reported by me) https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3930 ...probably more Please, if there's anything I can do to fix this, I will. I can apply and test patches, no problem. I'm attaching my own alsa-info.txt in case it helps. Thanks.
