From 05ac3846ffe53fc63e454eb195ce8a6bab7a6a88 Mon Sep 17 00:00:00 2001 From: Shenghao Ding Date: Fri, 27 Feb 2026 22:46:40 +0800 Subject: ALSA: hda/tas2781: A workaround solution to lower-vol issue among lower calibrated-impedance micro-speaker on TAS2781 On TAS2781, if the Speaker calibrated impedance is lower than default value hard-coded inside the TAS2781, it will cuase vol lower than normal. In order to fix this issue, the parameter of SineGainI need updating.

Some systems use the ASP as a special-purpose interconnect and on these systems the ASP registers are configured by a third party (the firmware, the BIOS, or another device using the amp's secondary host control interface). If the machine driver does not hook up the ASP DAI then the ASP registers must be omitted from the patch to prevent overwriting the third party configuration. If the machine driver includes the ASP DAI in a DAI link, this implies that the machine driver and higher components (such as alsa-ucm) are taking ownership of the ASP. In this case the ASP registers are patched to known defaults and the machine driver should configure the ASP.
