[alsa-devel] [PATCH v7 0/8] Fix year 2038 issue for sound subsystem
by Arnd Bergmann 19 Oct '21

19 Oct '21

This is a series I worked on with Baolin in 2017 and 2018, but we never quite managed to finish up the last pieces. During the ALSA developer meetup at ELC-E 2018 in Edinburgh, a decision was made to go with this approach for keeping best compatibility with existing source code, and then I failed to follow up by resending the patches. Now I have patches for all remaining time_t uses in the kernel, so it's absolutely time to revisit them. I have done more review of the patches myself and found a couple of minor issues that I have fixed up, otherwise the series is still the same as before. Conceptually, the idea of these patches is: - 64-bit applications should see no changes at all, neither compile-time nor run-time. - 32-bit code compiled with a 64-bit time_t currently does not work with ALSA, and requires kernel changes and/or sound/asound.h changes - Most 32-bit code using these interfaces will work correctly on a modified kernel, with or without the uapi header changes. - 32-bit code using SNDRV_TIMER_IOCTL_TREAD requires the updated header file for 64-bit time_t support - 32-bit i386 user space with 64-bit time_t is broken for SNDRV_PCM_IOCTL_STATUS, SNDRV_RAWMIDI_IOCTL_STATUS and SNDRV_PCM_IOCTL_SYNC_PTR because of i386 alignment. This is also addressed by the updated uapi header. - PCM mmap is currently supported on native x86 kernels (both 32-bit and 64-bit) but not for compat mode. This series breaks the 32-bit native mmap support for 32-bit time_t, but instead allows it for 64-bit time_t on both native and compat kernels. This seems to be the best trade-off, as mmap support is optional already, and most 32-bit code runs in compat mode anyway. - I've tried to avoid breaking compilation of 32-bit code as much as possible. Anything that does break however is likely code that is already broken on 64-bit time_t and needs source changes to fix them. I hope I addressed all review comments by now, so please pull this for linux-5.6. A git branch with the same contents is available for testing at [1].

[REGRESSION] "ALSA: HDA: Early Forbid of runtime PM" broke my laptop's internal audio
by Michael Catanzaro 17 Aug '21

17 Aug '21

Hi, On my System76 Gazelle Pro (gazp9) laptop, internal audio broke after upgrading to kernel 5.10. The laptop's speakers produce no sound. Audio from headphones still works fine. A quick test is to visit GNOME System Settings -> Sound -> Output, select Test, click Front Left or Front Right and notice there is no sound. I tested a mainline kernel revision from yesterday (5.11-rc5+) and the regression is not yet fixed. I bisected the regression to "ALSA: HDA: Early Forbid of runtime PM": https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… I created a downstream bug report here, including some bits from dmesg that may or may not be relevant in comment #2: https://bugzilla.redhat.com/show_bug.cgi?id=1918933 Audio devices: $ lspci | grep -i audio 00:03.0 Audio device: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor HD Audio Controller (rev 06) 00:1b.0 Audio device: Intel Corporation 8 Series/C220 Series Chipset High Definition Audio Controller (rev 05) OS: Fedora 33 I'm happy to provide any additional required info or test patches if you CC me, since I'm not a kernel developer and am not subscribed to these lists. Thanks.

[PATCH 0/7] ALSA/ASoC/SOF/SoundWire: fix Kconfig issues
by Pierre-Louis Bossart 28 Jul '21

28 Jul '21

In January, Intel kbuild bot and Arnd Bergmann reported multiple issues with randconfig. This patchset builds on Arnd's suggestions to a) expose ACPI and PCI devices in separate modules, while sof-acpi-dev and sof-pci-dev become helpers. This will result in minor changes required for developers/testers, i.e. modprobe snd-sof-pci will no longer result in a probe. The SOF CI was already updated to deal with this module dependency change and introduction of new modules. b) Fix SOF/SoundWire/DSP_config dependencies by moving the code required to detect SoundWire presence in ACPI tables to sound/hda. Integration note: This patchset touches directories maintained by Vinod, Takashi and Mark in separate trees, and will impact additional changes to use the auxiliary bus in drivers/soundwire/. I can think of two options, both of which are fine: 1. Mark merges the patches with Vinod and Takashi Acked-by tags, then Mark provides an immutable tag to Vinod. 2. Vinod merges the patches with Mark and Takashi Acked-by tags, then Vinod provides an immutable tag to Mark Acknowledgements: Thanks to Arnd for suggesting fixes and testing these patches with more randconfigs.

[PATCH] ALSA: hda: Enable runtime PM when codec probe fails
by Kai-Heng Feng 02 Jul '21

02 Jul '21

When codec probe fails, it doesn't enable runtime suspend, and can prevent graphics card from getting powered down: [ 4.280991] snd_hda_intel 0000:01:00.1: no codecs initialized $ cat /sys/bus/pci/devices/0000:01:00.1/power/runtime_status active So enable runtime PM when codec probe fails, to let graphics card be able to runtime suspend again. Merge azx_probe_continue() into azx_probe() and just let probe fail for this case could be a better approach. However that's a much bigger task so let's settle with a quirk workaround.

alsamixer: use background color instead of COLOR_BLACK
by GitHub pull_request - opened 08 Jun '21

08 Jun '21

alsa-project/alsa-utils pull request #77 was opened from r-burns: Hi! I have a cosmetic "improvement" I'd like to share. Scare quotes because this is possibly opinionated, but I'd still like to know what you think. I think on typical terminals, COLOR_BLACK is the same or quite similar to the background color, so this does not make much of a difference. But on "solarized" color schemes and similar, the COLOR_BLACK may be quite different from the background color, so in my opinion it looks odd to have the alsamixer panel stand out this way. For example, I'm using the "Nord" color scheme on a pitch black #000000 background, and here's how the mixer looks with/without this patch (blank terminal, htop, and ncmpcpp also provided for comparison): ![image](https://user-images.githubusercontent.com/52847440/107131140-dbf46500-6888-11eb-938a-9a3258bf7184.png) As you can see, the current alsamixer in the center looks a bit strange and sticks out against my chosen background color and the other TUIs I'm using. Htop and ncmpcpp agree on using the builtin `-1` background color for their own backgrounds, but alsamixer uses COLOR_BLACK which stands out from the actual background. The alsamixer on the bottom right is using this patch, and blends in seamlessly. Again, this is just my opinion! Feel free to close if this is wrong or superfluous. Nonetheless, I thought I'd share this patch, in case anyone else feels the same way.

[PATCH v3 0/7] PinePhone BT audio bringup
by Samuel Holland 24 May '21

24 May '21

This series uses the additional DAIs added to the sun8i-codec driver to add hardware routing for BT SCO (headset) audio on the PinePhone. The BT audio connection is represented by the "dummy" bt-sco codec. The connection to the Quectel EG-25G modem via AIF2 works as well, but I do not include it here because there is no appropriate codec driver in tree. We have been using an out-of-tree "dummy" codec driver for the modem similar to bt-sco, and I'm not sure if such a driver would be desired upstream. Changes from v2: - Also accept #sound-dai-cells in the binding. Since dt-core.yaml already sets the type of this property, it is not possible to use oneOf, nor make a specific value deprecated.
