ASoC: SOF: Intel: hda-stream: Fix incorrect variable used in error message

2025-10-02T11:35:42+00:00

[ Upstream commit 35fc531a59694f24a2456569cf7d1a9c6436841c ] The dev_err message is reporting an error about capture streams however it is using the incorrect variable num_playback instead of num_capture. Fix this by using the correct variable num_capture.

ASoC: SOF: Intel: hda: add softdep pre to snd-hda-codec-hdmi module

Add softdep to loading HDMI codec module first to ensure we can load it correctly.

ASoC: SOF: Intel: hda-dai: fix possible stream_tag leak

2023-02-22T11:56:00+00:00

commit 1f810d2b6b2fbdc5279644d8b2c140b1f7c9d43d upstream. The HDaudio stream allocation is done first, and in a second step the LOSIDV parameter is programmed for the multi-link used by a codec. This leads to a possible stream_tag leak, e.g. if a DisplayAudio link is not used. This would happen when a non-Intel graphics card is used and userspace unconditionally uses the Intel Display Audio PCMs without checking if they are connected to a receiver with jack controls. We should first check that there is a valid multi-link entry to configure before allocating a stream_tag. This change aligns the dma_assign and dma_cleanup phases.

ASoC: Intel/SOF: use set_stream() instead of set_tdm_slots() for HDAudio

2023-01-14T09:16:28+00:00

commit 636110411ca726f19ef8e87b0be51bb9a4cdef06 upstream. Overloading the tx_mask with a linear value is asking for trouble and only works because the codec_dai hw_params() is called before the cpu_dai hw_params(). Move to the more generic set_stream() API to pass the hdac_stream information.
