Hello all, I am experiencing an issue with my onboard sound card, where I have no sound output. Please see a copy of my alsa-info.sh for my current /etc/modprobe.d/*.conf config, located here: http://ix.io/3vAV I attempted troubleshooting using some config options that I saw listed in HDAudio.txt. Specifically, I tried model options for "generic". I also tried a few options for probe_mask, including "1" and "0x100". It seems that no matter which options I put in, I always get a CORB timeout from desg: [ 4.052955] snd_hda_intel 0000:00:1b.0: CORB reset timeout#1, CORBRP = 0 [ 4.053038] snd_hda_intel 0000:00:1b.0: no codecs initialized When I remove my probe_mask options, it first switches to polling mode, then single_cmd mode, and finally fails to initialize any codecs. I looked at the hda_intel.c file and saw a section for my onboard sound card (ref line 2515): 00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 05) I also want to share my hw-probe output, located here: https://linux-hardware.org/?probe=13e2d05856 It appears there are approximately 50 other users utilizing the same audio driver. From my searches across a few different websites, it seems that my particular audio chip should be very well supported and simply "work". I am now thinking this is a bug, as I can't see a reason why it should be failing in this manner. Thank you for any guidance you can provide.
