Merge tag 'asoc-fix-v7.3-rc2' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

2026-09-09T13:09:55Z

ASoC: Fixes for v7.3 An unusually large batch of fixes here, partly due to me not sending a pull request last week and partly due to Linus' fixes for the Ericsson systems. I'm fairly sure he's the only user there so it seemed low risk to handle as fixes. We also have a batch of error handling fixes from Cezary and issues with uninitialised stream_config->type from Shuming both of which had user error reports attached. Otherwise everything is a fairly normal combination of quirks and device specific fixes.

ALSA: hda: ext: Clean up streams if their initialization fails

2026-09-03T21:51:26Z

snd_hdac_ext_stream_init_all() does not rollback changes done when the allocation fails. Fix that to simplify its usage. Signed-off-by: Cezary Rojewski Acked-by: Takashi Iwai Link: https://patch.msgid.link/20260902081814.1590883-3-cezary.rojewski@intel.com Signed-off-by: Mark Brown

ALSA: hda: ext: Clean up links if their initialization fails

2026-09-03T21:51:24Z

snd_hdac_ext_bus_get_ml_capabilities() allocates the hlink nodes one-by-one but the procedure may fails due to -ENOMEM in the middle of it. Clean up the list before returning the error code to simply the function usage.

ALSA: hda: restore MFG widget enumeration after core split

2026-09-01T10:37:33Z

Before commit 7639a06c23c7 ("ALSA: hda - Move a part of hda_codec stuff into hdac_device"), widget enumeration selected the function group with codec->afg ? codec->afg : codec->mfg and read subordinate nodes from that group. The core split moved this logic into snd_hdac_refresh_widgets(), but hard-coded codec->afg there. For an MFG-only codec, codec->afg is zero, so the Root Node is queried and codec->start_nid/num_nodes are populated from the function-group range instead of the MFG's subordinate nodes. Restore the pre-split AFG-or-MFG selection.

ALSA: hda: Add Lisuan HDMI controller and codec support

2026-08-17T11:51:02Z

Lisuan GPUs expose an HD-audio controller at PCI ID 4c54:5010 and an HDMI/DP codec with codec ID 0x4c545020. Neither ID is currently matched by the HDA stack, leaving HDMI/DP audio unavailable on these devices. The existing downstream support uses the generic HDMI codec path and attaches no Lisuan-specific capability flags to the controller. Its dedicated AZX driver type only changes the short driver name. Use the corresponding generic upstream paths instead: bind 4c54:5010 to AZX_DRIVER_GENERIC, register 0x4c545020 as MODEL_GENERIC, and add the Lisuan codec vendor name. This keeps the enablement minimal and avoids a vendor-only AZX driver type with no vendor-specific behavior.

ALSA: hda: Drop __force casts

2026-08-13T14:43:27Z

Now that the bitwise parameter definitions are gone for PCM and control parameters, we don't have to cast with ugly __force prefix. Simply drop those superfluous casts. Reviewed-by: Cezary Rojewski Signed-off-by: Takashi Iwai Link: https://patch.msgid.link/20260812060557.80445-9-tiwai@suse.de

ALSA: hda/ext: preserve PPLCCTL bits when clearing reset

2026-08-13T07:11:38Z

snd_hdac_ext_stream_reset() polls PPLCCTL for STRST by masking the register value with AZX_PPLCCTL_STRST: val = readl(...) & AZX_PPLCCTL_STRST; The same masked value is then used when clearing STRST. Since val contains no bits other than STRST, clearing STRST from it always produces zero. The subsequent writel() therefore writes zero to the entire PPLCCTL register instead of clearing only the reset bit. PPLCCTL contains other stream control fields, including the stream tag in AZX_PPLCCTL_STRM_MASK. Those fields must not be modified as a side effect of clearing stream reset. Use snd_hdac_updatel() to clear STRST, matching the existing set-reset path and preserving all unrelated PPLCCTL bits.

ALSA: hda: simplify match functions and remove unreachable return

2026-08-12T05:28:48Z

hda_bus_match() has an unreachable 'return 1' after an if/else that covers both branches. Remove the superfluous return and simplify the control flow by dropping the else branch. hdac_codec_match() uses a redundant if/else to return 1 or 0. Simplify to a single return statement.

ALSA: hda/core: Log stream DMA errors on interrupt

2026-08-04T11:20:01Z

The stream descriptor status register reports FIFO and descriptor errors, but these are currently cleared silently along with the rest of the interrupt status. Log them, rate-limited, so DMA problems are visible instead of only manifesting as audible glitches. Observed on some AMD GPU HDMI audio controllers under specific low power circumstances.
