From: Jon Hunter Subject: [PATCH] ALSA: hda/tegra: Disable sync-write operation Date: Tue, 14 Jul 2020 17:08:41 +0100 Message-ID: <20200714160841.2293-1-jonathanh@nvidia.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: Sender: linux-tegra-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: Jaroslav Kysela , Takashi Iwai Cc: Thierry Reding , Mohan Kumar , alsa-devel-K7yf7f+aM1XWsZ/bQMPhNw@public.gmane.org, linux-tegra-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, Jon Hunter List-Id: linux-tegra@vger.kernel.org Commit f34a4c9dd4ca ("ALSA: hda: Enable sync-write operation as default for all controllers") enabled sync-write for all controllers and this is causing audio playback on the Tegra186 HDA device to fail. For now, disable sync-write support for Tegra to fix this.
