[PATCH] ALSA: dice: add stream format parameters for Weiss devices
by Michele Perrone 29 Feb '24

29 Feb '24

Hard-coded stream format parameters are added for Weiss Engineering FireWire devices. When the device vendor and model match, the parameters are copied into the stream format cache. This allows for setting all supported sampling rates up to 192kHz, and consequently adjusting the number of available I/O channels.

Could that be what's happening here? Thanks.

The speaker and hdmi of mt8186 platform are shared the same port of I2S, when connect the external display, use build-in speakers to play audio, they both playback at the same time.

[RESEND PATCH 0/1] ALSA: virtio: add support for audio controls
by Aiswarya Cyriac 15 Jan '24

15 Jan '24

From: Anton Yakovlev <anton.yakovlev(a)opensynergy.com> Implementation of support for audio controls in accordance with the extension of the virtio sound device specification[1] planned for virtio-v1.3-cs01. Design　of virtual audio controls is based on and derived from ALSA audio controls. It allows the driver to perform all standard operations, such as reading and writing audio control value, as well as working with metadata (represented in the TLV form). The driver part was tested on top of the Linux 5.10 kernel. As a device part was used OpenSynergy proprietary implementation.

[PATCH 00/31] Fix and improve Rockchip RK3128 support
by Alex Bee 13 Dec '23

Hi list, this series fixes some issues I found when testing my "new" RK3128 board with the mainline kernel and adds some core functionality like SMP bringup, usb and networking. The propably most distinctive change is the split up of the DTs for the different SoCs of this platform: RK3126 and RK3128. Even if I'm not adding a RK3126 board in this series: I think this change should be done as early as possible in order to avoid issues in future. Actually it should have been done like that in the first place. All patches have been tested on both SoCs: Patch 01-04 are dt-bindings additions for this SoC platform and the new board I'm addding here Patch 05-07 are some clock driver fixes (there is more to do, but I'm limiting it to the things which can work now) Patch 08 and 09 adding support for the usb 2 phy found in RK312x platform to the Rockchip Innosilicon usb phy driver. Patch 10-14 are DT patches which I did in the "old" rk3128.dtsi in order to be backportable. Patch 15 does the aforementioned split-up of the current rk3128.dtsi in rk312x.dtsi, rk3126.dtsi and rk3128.dtsi Patch 16-20 adds SMP bringup and cpu frequency scaling Patch 21-23 adds power controller, GPU and I2S nodes to the RK312x DT Patch 24-26 adds the second I2S, S/PDIF and gmac nodes to the RK3128 DT Patch 27-30 adds fixes for the usb controllers and adds a missing pincontrol for the sd card detection Patch 31 finnaly adds a DT for Genatech XPI-3128 board There are quite some HW blocks which can easily be added for this platform, but I guess this series is pretty huge already, so that it is limited to some core devices for now. I hope the single patches are small enough, that reviewing won't be a burden ;) The plan is to sync the DT changes to u-boot after they are merged where I'm planning to add "full" TPL/SPL for this platform (dram controller/phy driver is currently missing) I'm planing the add a RK3126 (tablet) board here as well, but I will have to add support for RK816 pmic first.

Regression apparently caused by commit 088a40980efbc2c449b72f0f2c7ebd82f71d08e2 "ASoC: amd: acp: add pm ops support for acp pci driver"
by Marian Postevca 05 Dec '23

05 Dec '23

I'm trying to develop a sound machine driver based on the acp legacy driver. The first version of the driver was sent for review on the alsa mailing list this spring: https://lore.kernel.org/all/20230320203519.20137-1-posteuca@mutex.one I'm trying to fix some of the issues that were brought up during the review back then, but when I ported the patches to the latest commit on the for-next branch, I noticed a regression where I couldn't hear any sound at all. So I started a bisect session and found that the first bad commit is: ASoC: amd: acp: add pm ops support for acp pci driver commit 088a40980efbc2c449b72f0f2c7ebd82f71d08e2 https://lore.kernel.org/lkml/20230622152406.3709231-11-Syed.SabaKareem@amd.… If I revert this commit sound works as expected. So I started tinkering a little bit with it and I believe that what happens is that the acp pci driver enters the autosuspend state and never leaves this state at all. I noticed this because if I increase the autosuspend delay to a much larger value, then the sound works until that delay passes. I added traces and I can see that when the delay expires the suspend callback snd_acp_suspend() gets called, but the resume callback snd_acp_resume() never gets called. I'm no expert in runtime power management (though I did read a bit on it), so I don't understand all the things that happen underneath, but one thing that is not clear to me is who's supposed to mark activity on this device and keep it from entering autosuspend if the user wants to play some sound? Shouldn't there be some counterpart that calls pm_runtime_mark_last_busy() ? I looked through the code and can't find who's calling pm_runtime_mark_last_busy(). Some help here would be welcome. Is there something missing in my machine driver code, or is the runtime pm handling in acp pci driver wrong?

[PATCH RFC] ALSA: scarlett2: Add ioctls for user-space access
by Geoffrey D. Bennett 27 Nov '23

27 Nov '23

In order to support functions such as firmware upgrade from user-space, add ioctls for submitting arbitrary proprietary requests through scarlett2_usb() and requesting/releasing exclusive access. --- Hi Takashi, I recently figured how to update the firmware on Scarlett Gen 2+ devices. I think the best way to implement this is with an ioctl giving access to the scarlett2_usb() function from user-space, plus two ioctls to request/release exclusive access. Does something like this seem reasonable? What ioctl magic/command values should I use? Should lock/unlock be separate, or one ioctl takes an argument for which operation to do? Thanks, Geoffrey.

kernel-5.9.13-200.fc33.x86_64 and alsa-lib-1.2.4-5.fc33.x86_64 on Fedora 33. Under Windows 10 the dongle works without any special drivers from Yamaha, everything appears to be downloaded by Windows automatically, so I was hoping the device could be made to work under Linux relatively easily.
