[PATCH 0/3] ASoC platform driver for Apple MCA
by Martin Povišer 19 Aug '22

19 Aug '22

Hi, for review I am posting another version of the ASoC platform driver to be used on Apple M1/M2 platforms (some previous version was attached to the macaudio RFC v2 [0]). Martin Changes since [0]: - addition of locking (extra commit) - transition to set_bclk_ratio (instead of getting the bclk ratio from set_sysclk) - using shared reset control and documenting the reset in binding - formatting, comments, and a minor fix to hw driving [0] https://lore.kernel.org/asahi/20220606191910.16580-1-povik+lin@cutebit.org/ Martin Povišer (3): dt-bindings: sound: Add Apple MCA I2S transceiver ASoC: apple: mca: Start new platform driver ASoC: apple: mca: Add locks on foreign cluster access .../devicetree/bindings/sound/apple,mca.yaml | 109 ++ MAINTAINERS | 8 + sound/soc/Kconfig | 1 + sound/soc/Makefile | 1 + sound/soc/apple/Kconfig | 9 + sound/soc/apple/Makefile | 3 + sound/soc/apple/mca.c | 1173 +++++++++++++++++ 7 files changed, 1304 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/apple,mca.yaml create mode 100644 sound/soc/apple/Kconfig create mode 100644 sound/soc/apple/Makefile create mode 100644 sound/soc/apple/mca.c -- 2.33.0

How trivial would it be to port the DICE driver from FFADO?
by forevernoob＠tutanota.com 19 Aug '22

19 Aug '22

Hello, I'm new to these kinds of mailing lists so please forgive me if I'm doing something dumb. I would love to see Allen & Heath Zed R16 as well as Midas Venice F32 support in ALSA. Currently (at least according to libffado-2.4.4/configuration), they are supported via the DICE driver: { # Allen and Heath Zed R16. Information from Brendan Pike. vendorid = 0x000004C4; modelid = 0x00000000; vendorname = "Allen and Heath"; modelname = "Zed R16"; driver = "DICE"; mixer = "Generic_Dice_EAP"; }, { # Midas Venice F32. Information from Jano Svitok. vendorid = 0x0010C73F; modelid = 0x00000001; vendorname = "Midas"; modelname = "Venice F32"; driver = "DICE"; mixer = "Generic_Dice_EAP"; }, In their source code I think it's this file: http://subversion.ffado.org/browser/branches/2.4.x/libffado/src/dice/dice_e… So my question would be: How difficult would it be to port this driver (more specifically: Port it sufficiently enough to support the aforementioned devices) ? Are we talking trivial enough for someone with minimal C experience, a dedicated team of ALSA devs or something else? Thanks in advance, FN

Raising volume past 100%
by David Griffith 18 Aug '22

18 Aug '22

After reinstalling Debian on a laptop, I once again had to face the problem of how to get volume out of the built-in speakers boosted. The last time I reinstalled, I somehow got the MATE volume control applet to let me turn the volume past 100% using the mouse wheel. Over the past two days I've been trying to rediscover what I neglected to write down. I'm already aware that by bringing up the Sound Preferences dialog, I can raise volume to 153% and no further. I also know that I can use pulseaudio-ctl(1) or pactl(1) to set the volume at any arbitrary level past 100%. I remember that I went looking for solutions other people found for this that involved editing /etc/asound.conf or ~/.asoundrc, but the best I can get with that is add an extra slider to alsamixer's display that acts as apreamplifier. I was going off of http://alien.slackbook.org/blog/adding-an-alsa-software-pre-amp-to-fix-low-…. What could I have possibly done to make this work the last time? -- David Griffith dave(a)661.org A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?
