We will register multiple codecs inside a single dai_link and differentiate these codecs by of_node. so we can't use dai-tdm-slot* to define the slot for each codec > > + > > + prefix_name: > > + $ref: /schemas/types.yaml#/definitions/string > > + description: device name prefix > > Why do you need this? When using multiple codecs, we utilize prefix_name to distinguish the dapm and kcontro of each individual codec.

Fine-grained control bar
by GitHub issues - opened 02 Mar '25

02 Mar '25

alsa-project/alsa-utils issue #295 was opened from egmontkob: The control bars of `alsamixer` are quite coarse. They jump by whole character cells. Often a notable amount of increase or decrease (pressing the Up or Down arrow) isn't reflected visually. I'd like to ask for an opion for more fine-grained looking control bars. If the terminal's / locale's claimed charset, as reported by `nl_langinfo(CODESET)`, is "UTF-8" (as it should be pretty much everywhere nowadays), you could use the Unicode characters [U+2581 to U+2588](https://www.unicode.org/charts/PDF/U2580.pdf) for this purpose. They jump by eighths of a cell's hight. Their foreground color would be the desired bar color (red/white/green) and their background would be the default (or black for `-B`). For consistency, this mode should probably replace the current checkerboard (ACS_CKBOARD) characters by the full block U+2588 and only set its foreground, but maybe this doesn't matter. There are several terminal emulators out there (at least VTE-based ones such as GNOME Terminal and many others; Konsole; and presumably much more) that don't take these glyphs from the font but rather draw them manually to perfectly align them at cell boundaries. In these terminals the bar would look perfectly. In other terminals there might be some ugly gaps at cell boundaries (subject to the selected font), but some people might still prefer this tiny visual glitch over the current coarseness of the bar (again: this would be an option, not a forced new behavior). Thanks for considering this feature request! Issue URL : https://github.com/alsa-project/alsa-utils/issues/295 Repository URL: https://github.com/alsa-project/alsa-utils

unclear example how to use remap plugin
by GitHub issues - opened 01 Mar '25

01 Mar '25

alsa-project/alsa-lib issue #441 was opened from dibalavs: Hello. I combiled 3 sound cards into one vrurtual 5.1 card for PCM, and now trying to make volume control also to use single virtual device, to set up volume for all chanel of virtual 5.1 card. I am trying to use remap control plugin mentioned at [source](https://github.com/alsa-project/alsa-lib/blob/master/src/control/co… But I unable to understand what does it mean: ``` ctl.name { type remap # Remap controls child STR # Child name # or child { # Child definition type STR ... } remap { # the ID strings are parsed in the amixer style like 'name="Headphone Playback Switch",index=2' SRC_ID1_STR DST_ID1_STR SRC_ID2_STR DST_ID2_STR ... } map { # join two stereo controls to one CREATE_ID1_STR { SRC_ID1_STR { vindex.0 0 # source channel 0 to merged channel 0 vindex.1 1 } SRC_ID2_STR { vindex.2 0 vindex.3 1 # source channel 1 to merged channel 3 } } # split stereo to mono CREATE_ID2_STR { SRC_ID3_STR { vindex.0 0 # stereo to mono (first channel) } } CREATE_ID3_STR { SRC_ID4_STR { vindex.0 1 # stereo to mono (second channel) } } } } ``` I do not understand what should I write as SRC and DST?: ``` # the ID strings are parsed in the amixer style like 'name="Headphone Playback Switch",index=2' SRC_ID1_STR DST_ID1_STR SRC_ID2_STR DST_ID2_STR ``` Can you give real example without placeholders like: "name", "SRC", "DST", "STR" ?
