From 809a0590ed238fcfaff18bd7bef1362d05c70965 Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Mon, 13 Sep 2021 11:10:42 +0900 Subject: [PATCH] ALSA: oxfw: fix transmission method for Loud models based on OXFW971 Loud Technologies Mackie Onyx 1640i (former model) is identified as the model which uses OXFW971. The analysis of packet dump shows that it transfers events in blocking method of IEC 61883-6, however the default behaviour of ALSA oxfw driver is for non-blocking method. This commit adds code to detect it assuming that all of loud models based on OXFW971 have such quirk. It brings no functional change except for alignment rule of PCM buffer.
