@Devin and Michael, That is because the X1C7 has too many configs: like different cpu, different ramsize or different disk size, each config has a unique cardlongname. And For this SRU, we only covered the configs we need to certify in our OEM enablement project.
LENOVO noticed this issue too, they told us the alsa-lib could find and load the ucm by the first 3 letters of BIOS_VERSION, so I am going to submit a new SRU with this solution soon. With that solution landed in the alsa-lib, all x1c7 could use one ucm. So could you please upload the output of cat /sys/devices/virtual/dmi/id/bios_version, let us see if the first 3 letters of bios_version are same or not among all x1c7 machines. @sil2100, Since the current SRU already covered all machines we enabled in the OEM project and they all worked well, please release it. Then I will cover the left machines in a new SRU. thx. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1859754 Title: add ucm to make alsa/sof driver work under PA (variants of Lenovo X1 Carbon 7th, Dell cnl and cml machines) To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1859754/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
