bdl_pos_adj is really a workaround for devices that report wrong DMA position (or at the wrong timing). I guess position_fix=1 may fix better.
Although the driver already has a dynamic switching of position_fix method, it checks only the very first read. If it gives a (more or less) sane value, it prefers the position-buffer method (corresponding to position_fix=2) rather than reading LPIB register (position_fix=1).
It seems, however, that more devices work sanely with LPIB reg nowdays. This wasn't the case formerly. So, it might be better to use position_fix=1 as default for modern systems...
Frank, Could you check that for you too adding "position_fix=1" fixes the problem?
To do so, edit /etc/modprobe.conf and add this line at end: options snd-hda-intel position_fix=1
You need to reboot for this to be taken into account.
