[alsa-devel] [PATCH v5 00/17] ASoC: fsl_ssi: Clean up - program flow level
by Nicolin Chen 17 Jan '18

17 Jan '18

[ Maciej, could you please send your Tested-by/Reviewed-by for AC97 once you confirm this series? And Caleb, this version does not need a test for non-AC97 cases. Thanks both! ] ==Change log== v5 * Reworked the series by taking suggestions from Maciej for AC97 + Fixed SSI lockup issue by changing cleanup sequence in PATCH-13 + Moved fsl_ssi_hw_clean() after unregistering the CODEC device in PATCH-13 + Set NULL as the parent of CODEC platform device to fix a NULL pointer dereference bug in PATCH-16 * Updated comments of three variables/pointers in struct fsl_ssi to describe them more accurately in PATCH-16 v4 * Reworked the series by taking suggestions from Maciej + Added TXBIT0 bit back to play safe in PATCH-14 + Made bool synchronous exclusive with AC97 mode in PATCH-16 v3 * Reworked the series by taking suggestions from Maciej + Added PATCH-01 to make RX and TX more clearly defined + Replaced "bool dir" with "int dir" in PATCH-04 + Replaced "!dir" with "int adir" in PATCH-05 + Put CBM_CFS behind the baudclk check to keep the same program flow in PATCH-14 + Removed all cpu_dai_drv changes in PATCH-15 v2 * Reworked the series by taking suggestions from Maciej + Added PATCH-01 to keep all ssi->i2s_net updated + Replaced bool tx with bool dir in PATCH-03 and PATCH-06 + Moved all initial register configurations from dai probe() to platform probe() so as to let AC97 CODEC successfully probe. * Added Tested-by from Caleb for TDM test cases. ==Background== The fsl_ssi driver was designed for PPC originally and then it has been updated to support different modes for i.MX Series, including SDMA, I2S Master mode, AC97 and older i.MXs with FIQ, by different contributors for different use cases in different coding styles. Additionally, in order to fix/work-around hardware bugs and design flaws, the driver made a lot of compromise so now its program flow looks very complicated and it's getting hard to maintain or update. So I am going to clean up the driver on both coding style level and program flow level. ==Introduction== This series of patches is the second set to clean up fsl_ssi driver in the program flow level. Any patch here may impact a fundamental test case like playback or record. ==Verification== This series of patches require fully tested. I have done such tests on i.MX6SoloX with WM8962 using imx_v6_v7_defconfig as: - Playback via I2S Master and Slave mode - Record via I2S Master and Slave mode - Simultaneous playback and record via I2S Master and Slave mode - Background playback with foreground record (starting at different time) via I2S Master and Slave mode - Background record with foreground playback (starting at different time) via I2S Master and Slave mode * All tests above by hacking offline_config to true in imx51. Caleb has tested v1-v4 with TDM lookback tests on i.MX6. Example of uncovered tests: AC97, PowerPC and FIQ.

When the MCLK is not yet available when the codec is probed, probe deferral will happen and in this case we should not print an error message.

[alsa-devel] Silencing plops / click sounds on start / stop of playing audio when snd_hda_intel.power_save=1
by Hans de Goede 17 Jan '18

17 Jan '18

Hi All, For Fedora 28 we plan to ship the kernel with snd_hda_intel.power_save defaulting to 1: https://fedoraproject.org/wiki/Changes/ImprovedLaptopBatteryLife We've had an update for F27 in updates-testing for a while which made the same change for F27, but we've received several bug reports about plops / click sounds on start / stop of playing audio: https://bugzilla.redhat.com/show_bug.cgi?id=1525104 I know others have probably already tried fixing this, but I'm wondering if there are any ideas how to fix this / things to try? Ideas of my own: 1) Mute the speakers / headphone output in the mixer before activating power-saving. Question how hard would it be to make this happen? 2) Put a delay between various steps involved in turning things off / on. Regards, Hans

[alsa-devel] [PATCH] ALSA: usb-audio: Add a quirk for Nura's first gen headset
by Martin Peres 16 Jan '18

16 Jan '18

The capture interface does not work, and the playback interface actually supports only 48kHz unlike what is advertised (44.1, 32, 22, 16, 8). The only unknown here is if there are other devices that use the same product ID, but given that this ID is currently unknown, I would assume it is specially allocated for the nura headset.
