Control: tag -1 +moreinfo Hello,
After exploring this issue a bit it seems that there are multiple issues with the provided configuration for the 18i20 depending on the generation. Instead of reverting the whole profile, I think that one fix could be the following regex fix that makes the profile match the gen1 18i20: https://github.com/alsa-project/alsa-ucm-conf/commit/40002e48eee529e6d97cd51b488e1b20d594cc47 Can you confirm, if you have a gen1, that this change fixes the issue and makes the 18i20 gen1 recognized and work? You can probably edit the file by hand and change the big `C` to a small `c` and check: diff --git a/ucm2/USB-Audio/USB-Audio.conf b/ucm2/USB-Audio/USB-Audio.conf index fe2cd46..65facee 100644 --- a/ucm2/USB-Audio/USB-Audio.conf +++ b/ucm2/USB-Audio/USB-Audio.conf @@ -345,11 +345,11 @@ If.focusrite-scarlett-18i20 { Condition { Type RegexMatch String "${CardComponents}" - # 800C 1st Gen + # 800c 1st Gen # 8201 2nd Gen # 8215 3rd Gen # 821d 4th Gen - Regex "USB1235:8(00C|2(01|1(5|d)))" + Regex "USB1235:8(00c|2(01|1(5|d)))" } True.Define.ProfileName "Focusrite/Scarlett-18i20" } If you do not have a 18i20 gen1 but something else then this issue probably needs more investigation… In the meantime you could use the version in trixie-backports and check if the issue is still present. Thanks, Agathe.
