| |
| commit 082c192c0dd03f685514c9ce2eb0a80fd28e2175 upstream. |
| |
| Intel ACE4 based products set more strict constraints on HDA BDLE start |
| address and length alignment. Modify capability flags to drop |
| AZX_DCAPS_NO_ALIGN_BUFSIZE for Intel Nova Lake platforms. |
| |
| Fixes: 7f428282fde3 ("ALSA: hda: controllers: intel: add support for Nova Lake") |
