The controller's DMA timing degrades after resume, causing premature IRQ detection in azx_position_ok() which results in silent HDMI/DP audio output despite userspace reporting a valid playback state and correct ELD data. Increase bdl_pos_adj to 64 for AZX_DRIVER_NVIDIA, matching the value already used by Intel Apollo Lake for the same class of timing issue.
