a) It looks like the patches are changing many more things than "just" CS35L56 support. I'm not familiar with firmware-sof and these binary files, but that's what it looks like (output truncated below for brevity):

Why are all these other files necessary? b) Given that not just CS35L56 files are being added/changed, but many others, for apparently other hardware, that doesn't seem to match the regression analysis: > It only affects the Dell Bolan platforms with the new CS35L56 amplifier. > Should be low low risk of > regression Is that statement still true? Only CS35L56 could be affected by a regression? ** Changed in: firmware-sof (Ubuntu Oracular) Status: New => Incomplete ** Changed in: firmware-sof (Ubuntu Noble) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2077829 Title: Missing CS35L56 sof firmware for Dell Bolan platform To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/2077829/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
