[PATCH 1/1] ALSA: remove ALC289_FIXUP_DUAL_SPK for Dell 5530
by Callum Osmotherly 05 Oct '22

05 Oct '22

From: Callum Osmotherly <callum.osmotherly(a)gmail.com> After some feedback from users with Dell Precision 5530 machines, this patch reverts the previous change to add ALC289_FIXUP_DUAL_SPK. While it improved the speaker output quality, it caused the headphone jack to have an audible "pop" sound when power saving was toggled.

[PATCH] ALSA: hda/hdmi: run eld notify in delay work
by Brent Lu 05 Oct '22

05 Oct '22

During resolution change, display driver would disable HDMI audio then enable it in a short time. There is possibility that eld notify for HDMI audio enable is called when previous runtime suspend is still running. In this case, the elf nofity just returns and not updating the status of corresponding HDMI pin/port. Here we move the eld nofity to a delay work so we don't lose it.

[PATCH] ALSA: usb-audio: Split endpoint setups for hw_params and prepare (take#2)
by Takashi Iwai 05 Oct '22

05 Oct '22

This is a second attempt to fix the bug appearing on Android with the recent kernel; the first try was ff878b408a03 and reverted at commit 79764ec772bc. The details taken from the v1 patch: One of the former changes for the endpoint management was the more consistent setup of endpoints at hw_params. snd_usb_endpoint_configure() is a single function that does the full setup, and it's called from both PCM hw_params and prepare callbacks. Although the EP setup at the prepare phase is usually skipped (by checking need_setup flag), it may be still effective in some cases like suspend/resume that requires the interface setup again. As it's a full and single setup, the invocation of snd_usb_endpoint_configure() includes not only the USB interface setup but also the buffer release and allocation. OTOH, doing the buffer release and re-allocation at PCM prepare phase is rather superfluous, and better to be done only in the hw_params phase. For those optimizations, this patch splits the endpoint setup to two phases: snd_usb_endpoint_set_params() and snd_usb_endpoint_prepare(), to be called from hw_params and from prepare, respectively. Note that this patch changes the driver operation slightly, effectively moving the USB interface setup again to PCM prepare stage instead of hw_params stage, while the buffer allocation and such initializations are still done at hw_params stage. And, the change of the USB interface setup timing (moving to prepare) gave an interesting "fix", too: it was reported that the recent kernels caused silent output at the beginning on playbacks on some devices on Android, and this change casually fixed the regression. It seems that those devices are picky about the sample rate change (or the interface change?), and don't follow the too immediate rate changes. Meanwhile, Android operates the PCM in the following order: - open, then hw_params with the possibly highest sample rate - close without prepare - re-open, hw_params with the normal sample rate - prepare, and start streaming This procedure ended up the hw_params twice with different rates, and because the recent kernel did set up the sample rate twice one and after, it screwed up the device. OTOH, the earlier kernels didn't set up the USB interface at hw_params, hence this problem didn't appear. Now, with this patch, the USB interface setup is again back to the prepare phase, and it works around the problem automagically. Although we should address the sample rate problem in a more solid way in future, let's keep things working as before for now. *** What's new in the take#2 patch: - The regression caused by the v1 patch (bko#216500) was due to the missing check of need_setup flag at hw_params. Now the check is added, and the snd_usb_endpoint_set_params() call is skipped when the running EP is re-opened. - There was another bug in v1 where the clock reference rate wasn't updated at hw_params phase, which may lead to a lack of the proper hw constraints when an application doesn't issue the prepare but only the hw_params call. This patch fixes it as well by tracking the clock rate change in the prepare callback with a new flag "need_update" for the clock reference object, just like others. - The configure_endpoints() are simplified and folded back into snd_usb_pcm_prepare().

Change to RemainAfterExit=yes in alsa-restore.service.in
by GitHub pull_request - opened 04 Oct '22

04 Oct '22

alsa-project/alsa-utils pull request #171 was opened from stele95: Fresh Manjaro installation. Default volume value was 75%, no matter to what value I change it, it resets to 75% on reboot/shutdown. After changing to `RemainAfterExit=yes` from `RemainAfterExit=true` in `alsa-restore.service`, the volume value is properly saved and restored on reboot/shutdown. I did check the following [link](https://www.freedesktop.org/software/systemd/man/systemd.service.html) and it says: > RemainAfterExit= > Takes a boolean value that specifies whether the service shall be considered active even when all its processes exited. Defaults to no. But if you look at `Example 4. Stoppable oneshot service`, it clearly sets `RemainAfterExit=yes` with `Type=oneshot`.

[PATCH] Revert "ASoC: soc-component: using pm_runtime_resume_and_get instead of pm_runtime_get_sync"

From: Peter Ujfalusi <peter.ujfalusi(a)gmail.com> This reverts commit 08fc2a7448afc1660ec2f1b5c437fcd14155a7ee. The reverted commit causes the following warnigs: Runtime PM usage count underflow! This is due to the fact that the pm_runtime_resume_and_get() is calling pm_runtime_put_noidle() in case of < 0 return value of pm_runtime_get_sync() which includes the -EACCES. The change is wrong as -EACCES is returned in case of 'nested' get_sync() and it is a valid use of PM runtime.
