[PATCH 5.10 1/1] ASoC: ops: Check for negative values before reading them
by d.privalov 12 Mar '25

12 Mar '25

From: Mark Brown <broonie(a)kernel.org> commit 1601033da2dd2052e0489137f7788a46a8fcd82f upstream. The controls allow inputs to be specified as negative but our manipulating them into register fields need to be done on unsigned variables so the checks for negative numbers weren't taking effect properly. Do the checks for negative values on the variable in the ABI struct rather than on our local unsigned copy.

Channel count in Focusrite Scarlett Gen 4 (1235:8218) SplitPCM configuration

alsa-project/alsa-ucm-conf issue #515 was edited from pv: The configuration https://github.com/alsa-project/alsa-ucm-conf/blob/master/ucm2/USB-Audio/Fo… specifies `HWChannels 2` for the Mic1 and Mic2 devices. This gets translated to `CaptureChannels 2` for `alsaucm open '<<<SplitPCM=1>>>hw:2'`. However, we've got a report https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/4597#note_2815906 that looks like snd_pcm_hw_params_set_channels(pcm_handle, hwparams, 2) for the CapturePCM "_ucm0001.hw:Gen,0" fails with error. The PCM can be opened with 4 channels, though. Without `SplitPCM=1`, it also probably works but I'm not sure what channel count the `dshare` plugin is using. The issue also affects the `Direct` profile, which also specifies `CaptureChannels 2`. Is the `HWChannels 2` for Mic1/2 input direction right?

PORT: GTK2 to GTK3

alsa-project/alsa-tools pull request #27 was opened from genbtc: I've undertaken a task of porting alsa-tools programs from GTK2 to GTK3. These patches start with a base of 5eaadd15bda4cf0424ee2470a6d304a0c2ce10cb (master) Date: Mon Jan 27 (latest pull) Results: Compilation completes successfully, Linked to GTK3, but I do not have the hardware cards to test run them. All work has been done by me, and I request a code review on the GDK 2 Pixmap to GDK 3 Pixbuf + Cairo surfaces. Like it needs new logic and new plan. not simply change statement A to B (whatever I did to get it to compile) I tried to comply with the existing style, and There was also a fair bit of inconsequential whitespace removed like (\n\t\n) or trailing space chars as I discovered them. Looking forward to upstreaming these changes somehow if you would like to work on this. - genBTC @ gentoo Request URL : https://github.com/alsa-project/alsa-tools/pull/27 Patch URL : https://github.com/alsa-project/alsa-tools/pull/27.patch Repository URL: https://github.com/alsa-project/alsa-tools

Multiple CODECs on > the same link is the main use case for set_tdm_slot(). Thanks for the advice.The method you mentioned could work. I will modify my driver.
