From 0e0aa7108a147633146285f8956451bd8e86e6a7 Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Thu, 23 Nov 2023 10:47:49 +0100 Subject: [PATCH] ASoC: codecs: wsa883x: make use of new mute_unmute_on_trigger flag commit 805ce81826c896dd3c351a32814b28557f9edf54 upstream. In the current setup the PA is left unmuted even when the Soundwire ports are not started streaming. This can lead to click and pop sounds during start. There is a same issue in the reverse order where in the PA is left unmute even after the data stream is stopped, the time between data stream stopping and port closing is long enough to accumulate DC on the line resulting in Click/Pop noise during end of stream. making use of new mute_unmute_on_trigger flag is helping a lot with this Click/Pop issues reported on this Codec Signed-off-by: Srinivas Kandagatla Tested-by: Johan Hovold Link: https://lore.kernel.org/r/20231027105747.32450-3-srinivas.kandagatla@linaro.org Signed-off-by: Mark Brown Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman --- sound/soc/codecs/wsa883x.c | 7 +------ 1 file changed, 1 insertion(+), 6 deletions(-) diff --git a/sound/soc/codecs/wsa883x.c b/sound/soc/codecs/wsa883x.c index 197fae2..cb83c56 100644 --- a/sound/soc/codecs/wsa883x.c +++ b/sound/soc/codecs/wsa883x.c @@ -1203,9 +1203,6 @@ static int wsa883x_spkr_event(struct snd_soc_dapm_widget *w, break; } - snd_soc_component_write_field(component, WSA883X_DRE_CTL_1, - WSA883X_DRE_GAIN_EN_MASK, - WSA883X_DRE_GAIN_FROM_CSR); if (wsa883x->port_enable[WSA883X_PORT_COMP]) snd_soc_component_write_field(component, WSA883X_DRE_CTL_0, WSA883X_DRE_OFFSET_MASK, @@ -1218,9 +1215,6 @@ static int wsa883x_spkr_event(struct snd_soc_dapm_widget *w, snd_soc_component_write_field(component, WSA883X_PDM_WD_CTL, WSA883X_PDM_EN_MASK, WSA883X_PDM_ENABLE); - snd_soc_component_write_field(component, WSA883X_PA_FSM_CTL, - WSA883X_GLOBAL_PA_EN_MASK, - WSA883X_GLOBAL_PA_ENABLE); break; case SND_SOC_DAPM_PRE_PMD: @@ -1346,6 +1340,7 @@ static const struct snd_soc_dai_ops wsa883x_dai_ops = { .hw_free = wsa883x_hw_free, .mute_stream = wsa883x_digital_mute, .set_stream = wsa883x_set_sdw_stream, + .mute_unmute_on_trigger = true, }; static struct snd_soc_dai_driver wsa883x_dais[] = { -- 2.7.4
