alsa-project/alsa-utils issue #84 was opened from giggywithit: Hello I design and build audio equipment and would like to know where or how I would go about getting access to the sound states to control a GPIO for a raspberry Pi. What I would like ideally is to control a GPIO state based upon actual non-zero data playback. My desire is to use the GPIO to control a mute function to silence the interactive periods in DAC activity. I know little to nothing about programming but imagine the function is intelligent enough to discern the difference between an open device and actual music playback. Other methods keep open the device to keep from switching off and on, however, I am looking for a more professional and detailed method to create. Any pointers helpful thank you S Issue URL : https://github.com/alsa-project/alsa-utils/issues/84 Repository URL: https://github.com/alsa-project/alsa-utils

[PATCH AUTOSEL 4.4 05/10] ASoC: sgtl5000: set DAP_AVC_CTRL register to correct default value on probe
by Sasha Levin 25 Mar '21

25 Mar '21

From: Benjamin Rood <benjaminjrood(a)gmail.com> [ Upstream commit f86f58e3594fb0ab1993d833d3b9a2496f3c928c ] According to the SGTL5000 datasheet [1], the DAP_AVC_CTRL register has the following bit field definitions: | BITS | FIELD | RW | RESET | DEFINITION | | 15 | RSVD | RO | 0x0 | Reserved | | 14 | RSVD | RW | 0x1 | Reserved | | 13:12 | MAX_GAIN | RW | 0x1 | Max Gain of AVC in expander mode | | 11:10 | RSVD | RO | 0x0 | Reserved | | 9:8 | LBI_RESP | RW | 0x1 | Integrator Response | | 7:6 | RSVD | RO | 0x0 | Reserved | | 5 | HARD_LMT_EN | RW | 0x0 | Enable hard limiter mode | | 4:1 | RSVD | RO | 0x0 | Reserved | | 0 | EN | RW | 0x0 | Enable/Disable AVC | The original default value written to the DAP_AVC_CTRL register during sgtl5000_i2c_probe() was 0x0510. This would incorrectly write values to bits 4 and 10, which are defined as RESERVED. It would also not set bits 12 and 14 to their correct RESET values of 0x1, and instead set them to 0x0. While the DAP_AVC module is effectively disabled because the EN bit is 0, this default value is still writing invalid values to registers that are marked as read-only and RESERVED as well as not setting bits 12 and 14 to their correct default values as defined by the datasheet. The correct value that should be written to the DAP_AVC_CTRL register is 0x5100, which configures the register bits to the default values defined by the datasheet, and prevents any writes to bits defined as 'read-only'. Generally speaking, it is best practice to NOT attempt to write values to registers/bits defined as RESERVED, as it generally produces unwanted/undefined behavior, or errors. Also, all credit for this patch should go to my colleague Dan MacDonald <dmacdonald(a)curbellmedical.com> for finding this error in the first place.

[PATCH AUTOSEL 4.4 04/10] ASoC: rt5651: Fix dac- and adc- vol-tlv values being off by a factor of 10
by Sasha Levin 25 Mar '21

25 Mar '21

From: Hans de Goede <hdegoede(a)redhat.com> [ Upstream commit eee51df776bd6cac10a76b2779a9fdee3f622b2b ] The adc_vol_tlv volume-control has a range from -17.625 dB to +30 dB, not -176.25 dB to + 300 dB. This wrong scale is esp. a problem in userspace apps which translate the dB scale to a linear scale. With the logarithmic dB scale being of by a factor of 10 we loose all precision in the lower area of the range when apps translate things to a linear scale. E.g. the 0 dB default, which corresponds with a value of 47 of the 0 - 127 range for the control, would be shown as 0/100 in alsa-mixer. Since the centi-dB values used in the TLV struct cannot represent the 0.375 dB step size used by these controls, change the TLV definition for them to specify a min and max value instead of min + stepsize. Note this mirrors commit 3f31f7d9b540 ("ASoC: rt5670: Fix dac- and adc- vol-tlv values being off by a factor of 10") which made the exact same change to the rt5670 codec driver.

From: Lucas Tanure <tanureal(a)opensource.cirrus.com> [ Upstream commit 19325cfea04446bc79b36bffd4978af15f46a00e ] This delay is part of the power-up sequence defined in the datasheet. A runtime_resume is a power-up so must also include the delay.
