From ad24919540fb4df83981d469b5253cc1aecca939 Mon Sep 17 00:00:00 2001 From: Richard Fitzgerald Date: Mon, 5 Jun 2023 15:32:38 +0100 Subject: [PATCH 1/6] firmware: cs_dsp: Log correct region name in bin error messages In cs_dsp_load_coeff() region_name should be set in the XM/YM/ZM cases otherwise any errors will log the region as "Unknown". While doing this also change one error message that logged the region type ID to log the region_name instead. This makes it consistent with other messages in the same function.

The reason is that the driver expects the full D0 power state change only at hw_params, while the normal PCM resume procedure doesn't call hw_params. For fixing the bug, we add the same power state update to D0 at the prepare callback, which is certainly called by the resume procedure. Note that, with this change, the power state change in the hw_params becomes almost redundant, since snd_usb_hw_params() doesn't touch the parameters (at least it tires so). But dropping it is still a bit risky (e.g. we have the media-driver binding), so I leave the D0 power state change in snd_usb_hw_params() as is for now.

Prior to this change Linux kernel was not enabling native DSD playback for HEM devices, and as a result, DSD audio was being converted to PCM "on the fly". HEM devices, when connected to the system, would only play audio in PCM format, even if the source material was in DSD format. With the addition of new VENDOR_FLG in the quircks.c file, the devices are now correctly recognized, and raw DSD data is transmitted to the device, allowing for native DSD playback.
