Merge tag 'asoc-fix-v7.1-merge-window' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

ASoC: Fixes for v7.1 A fairly small collection of fixes, device IDs and quirks that came in during the merge window, the most remarkable of which is one for SDCA boolean firmware flags which is remarkable mainly because it is partially in regmap.

ASoC: sdw_utils: cs42l43: allow spk component names to be combined

2026-04-22T15:00:10+00:00

Move handling of cs42l43-spk component string into SOF mechanism [1] which will allow it to be aggregated with other speakers. Likewise handle the cs35l56-bridge special case which should not be combined to keep compatibility with UCM.

ASoC: qcom: x1e80100: limit speaker volumes

2026-04-22T14:44:05+00:00

Limit the digital gain and PA volumes to a combined -3 dB in the machine driver to reduce the risk of speaker damage until we have active speaker protection in place (or higher safe levels have been established). Based on commit c481016bb4f8 ("ASoC: qcom: sc8280xp: limit speaker volumes") which addressed the same issue on the sc8280x SoC with some minor changes as explained below. The Digital Volume behaves almost identical to sc8280x since both use the same lpass-wsa-macro, but x1e80100 has two sets of controls prefixed with WSA and WSA2. For PA x1e80100 machines use wsa884x amplifiers which expose a linear scale from -9 dB to 9 dB with a 1.5 dB step size giving us 0 dB = -9 dB + 6 * 1.5 dB. On x1e80100 there are two different speaker topologies we need to handle: 2-Speakers: SpkrLeft, Spkr Right 4-Speakers: WooferLeft, WooferRight, TweeterLeft, TweeterRight Signed-off-by: Tobias Heider Tested-by: Srinivas Kandagatla Reviewed-by: Srinivas Kandagatla Link: https://patch.msgid.link/20260422-x1e80100-audio-limit-v2-1-333258b97697@canonical.com Signed-off-by: Mark Brown

ASoC: Correct bug parsing DisCo booleans

2026-04-20T17:40:07+00:00

Charles Keepax says: MIPI DisCo uses the unfortunate convention of allowing boolean properties to be present but having a zero value. Opposed to the normal convention of simply not specifying the property. Fix an issue in the SDCA code where mipi-sdca-control-deferrable is not parsed correctly. However, we also have some shipping ACPIs where these properties are not specified correctly. Update the MBQ regmap to attempt defers albeit with a warning in the case where a control attempts to defer but is not marked at such. There is little down side to this as if defer is genuinely not supported then the control will just return the same error again.

ASoC: SDCA: Fix reading of mipi-sdca-control-deferrable

2026-04-20T17:40:03+00:00

The discussion in [1] highlighted that the SDCA code shouldn't be using fwnode_property_read_bool() for DisCo controls, as the spec allows setting the value to zero meaning the property should not be used. Correct a small bug in the SDCA code that will mark such controls as deferrable.

ALSA: hda/tas2781: Fix sound abnormal issue on some SPI device

2026-04-20T15:59:19+00:00

In the SPI driver probe, the chip ID must be set to TAS2781. Without this initialization, calibration data fails to load correctly, causing audio abnormalities on some devices. And update the register bulk read API to handle the distinct requirements of SPI and I2C devices.
