~~The rate list is set by topology ? I don't see limiting in the SOF HDA driver for the analog paths based on codec capabilities. The **snd_hdac_query_supported_pcm** is used only...

Ok, at the moment, I just need input if the alternate PCM stream is an option also for SOF or I should dig to find another way to handle the...

I expect that BE and LE for the second HDA playback stream will be created together. The difference will be that the alternate PCM device is usable at runtime or...

This logic does not match HDMI devices. They are not usable until something is connected, thus samples are ending in nowhere, too.

This path won't be functional until the 'Independent HP' control is turned on, thus some code must enable it (UCM will handle this and UCM will define the different route...

> Or is the presence of the control already an indication that the second path is available. Yes, look for `alt_dac_nid` handling in `hda_generic.c` . If this variable is set,...

Yes, create `/lib/firmware/hda-test.patch` with (you may need to correct codec IDs from `/proc/asound/card?/codec#?` file): ``` [codec] 0x10ec0289 0x10280926 0 [hint] indep_hp = yes ``` Force generic driver on SOF and...

I'd like to propose this code change for Legacy HDA: ``` From 52d43aafd9d7cec0bc8112760db4a45fa42a2cd9 Mon Sep 17 00:00:00 2001 From: Jaroslav Kysela Date: Mon, 5 Feb 2024 11:58:41 +0100 Subject: [PATCH]...

At first, it's a bit late to change this configuration scheme now. If we revert the database as you suggest, the hardware with S/PDIF will not work (regression), because there's...
