Hi, As requested, here is the exact hardware identity (PCI ID) of the audio controller from my Dell OptiPlex 755:
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller [8086:293e] (rev 02) I hope this output helps you implement the appropriate hardware blacklist or power-saving quirk in future kernel releases. Thank you for your help and time! Best regards
