sof-hda-dsp: Support systems without integrated graphics audio #15
Conversation
|
@juimonen and @perexg please review. You can test this on any system that supports SOF (and recent kernel) with following kernel option: options snd_sof_intel_hda_common codec_mask=0x1 ... this will disable HDMI HDA codec. On older kernel SOF probe still fails, but this is fixed in recent kernel. Or alternative a system like HP Omen17 that has no integrated graphics. |

@plbossart oops, fixed
On systems where integrated graphics audio is not present or is disabled, the HDMI PCM nodes are disabled. Add rules to detect these systems by checking presence of HDMI jack controls with UCM2 rules. Signed-off-by: Kai Vehmanen <kai.vehmanen@linux.intel.com>

And the support for the fourth HDMI output? I think that it was added to the driver, wasn't? |

Yes, that needs to be added in a separate patch. |

@perexg Btw, any plan for a new alsa-ucm release? It seems quite a few people are hitting issues without this patch in alsa-ucm (e.g. thesofproject/linux#1985 and thesofproject/linux#1917 at least, but in general any laptop with NVidia GPU). Without this, Pulseaudio keeps trying to open the non-existing i915 HDMI PCM devices. |

@kv2019i alsa-ucm-conf or alsa-lib? |
