Hi Vijendar,
Thanks for your reply. I have created a Bugzilla ticket for this issue
and attached all the requested logs (ALSA info, lspci, ACPI dump, and
dmidecode).
You can find the ticket here:
https://bugzilla.kernel.org/show_bug.cgi?id=221132
Please let me know if any further information is needed.
Thanks,
Jason
