[PATCH v1] ALSA: hda: cs35l41: Support mute notifications for CS35L41 HDA
by Stefan Binding 06 Sep '23

06 Sep '23

From: Vitaly Rodionov <vitalyr(a)opensource.cirrus.com> Some laptops require a hardware based mute system, where when a hotkey is pressed, it forces the amp to be muted. For CS35L41, when the hotkey is pressed, an acpi notification is sent to the CS35L41 Device Node. The driver needs to handle this notification and call a _DSM function to retrieve the mute state. Since the amp is only muted during playback, the driver will only mute or unmute if playback is occurring, otherwise it will save the mute state for when playback starts. Only one handler can be registered for the acpi notification, but all amps need to receive that notification, we can register a single handler inside the Realtek HDA driver, so that it can then notify through the component framework.

Channels are swaped in alsamixer with asus strix raid dlx audio card
by GitHub issues - opened 06 Sep '23

06 Sep '23

alsa-project/alsa-ucm-conf issue #349 was opened from raveit65: First, i hope this is the right repository for the issue. I am using a 2.1 loudspeaker setup with fedora 38 and pipewire sound server. With alsamixer or qasmixer the subwoofer channel is swaped. With a 2.1 channel setup the subwoofer channel in qasmixer is silent. With a 5.1 channel setup the subwoofer channel is swapped with the back/right channel, and the subwoofer channel seems only mute/un-mute the subwoofer. But the volume itself is controlled by the back/right channel. I am thinking that the middle/front channel is also swapped with back/left channel, but not tested because i don't have an (active) middle/front speaker. It looks like a channel rooting issue but i don't have the knowledge about alsa to fix that with a asound.conf. The card is a usb-audio device. Beside from this issue the card works well under linux. I don't use the control box for headphones. I am happy to provide more information if requested. If you think this is alsa related i can close this kernel bug report. https://bugzilla.kernel.org/show_bug.cgi?id=217868 alsa-info: [alsa-info.txt](https://github.com/alsa-project/alsa-ucm-conf/files/12535277… Issue URL : https://github.com/alsa-project/alsa-ucm-conf/issues/349 Repository URL: https://github.com/alsa-project/alsa-ucm-conf

removing COPYING.GPL from alsa-plugins?
by Michael Wang 06 Sep '23

06 Sep '23

Hi Alsa-devel, While reviewing the license for alsa-plugins-1.2.7.1, I noticed that it has both a COPYING and a COPYING.GPL file. The only plugin that possibly has a GPLv2 license is rate/rate_samplerate.c, which has this at the top of the file: * Rate converter plugin using libsamplerate * * Copyright (c) 2006 by Takashi Iwai <tiwai(a)suse.de> * * This plugin code is supposed to be used and distributed primarily * under GPL v2 or later, in order to follow the license of libsamplerate. * However, if you already own a commercial license to use libsamplerate * for dynamic linking, this plugin code can be used and distributed also * under LGPL v2.1 or later. So it seems like rate_samplerate.c is licensed as GPLv2 in order to be consistent with libsamplerate. But in 2016, libsamplerate dropped its commercial license requirement and was released with the 2-Clause BSD license. (See http://libsndfile.github.io/libsamplerate//license.html) So I was wondering if the license for rate_samplerate.c can be updated to remove the GPLv2, which means the COPYING.GPL file can also be removed from the package? Thank you!
