alsa-project/alsa-ucm-conf issue #590 was opened from tomaszdrozdz: Hello all. In nutshell: - I can not set 5.1 sound on my Fedora. - My sound card is Realtek ALC897. First I described it here: https://discussion.fedoraproject.org/t/5-1-7-1-sound-speakers/156932/4 Then here: https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/4788 And so I got here. If you need more info or action to be taken from me please let me know. Help, assist - Please.

[PATCH] ASoC: rt5650: Eliminate the high frequency glitch
by derek.fang＠realtek.com 10 Jul '25

10 Jul '25

From: Derek Fang <derek.fang(a)realtek.com> The glitch was detected in the high frequency of the HP playback. This patch adjusts the DAC dither setting to avoid this situation for almost all cases.

[PATCH v2] ALSA: hda/tas2781: Fix calibration data parser issue
by Baojun Xu 07 Jul '25

07 Jul '25

We will copy calibration data from position behind to front. We has created a variable (tmp_val) point on top of calibration data buffer, and tmp_val[1] is max of node number in original calibration data structure, it will be overwritten after first data copy, so can't be used as max node number check in for loop. So we create a new variable to save max of node number (tmp_val[1]), used to check if max node number was reached in for loop. And a point need to be increased to point at calibration data in node. Data saved position also need to be increased one byte.

test: update midifile library to ANSI C
by GitHub pull_request - opened 06 Jul '25

06 Jul '25

alsa-project/alsa-lib pull request #463 was opened from atsampson: The `midifile` library used by the `playmidi1` program dates from 1989, and used pre-ANSI function definitions and prototypes. GCC 15 now defaults to C23 where `()` means the same as `(void)` in prototypes, which causes type mismatch errors. Update the code to use ANSI function definitions and prototypes, so it'll compile happily as anything from ANSI C to C23. This revealed that `playmidi1`'s `do_tempo` had the wrong argument type, so correct that as well. Fixes #452. Request URL : https://github.com/alsa-project/alsa-lib/pull/463 Patch URL : https://github.com/alsa-project/alsa-lib/pull/463.patch Repository URL: https://github.com/alsa-project/alsa-lib
