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:
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)
In the alsa-info.sh log, I can see this [ 3.950319] snd_hda_intel 0000:00:1b.0: codec_mask forced to 0x0
I am not sure how this might happen, this looks like a bad configuration to me?
/* check forced option */ if (chip->codec_probe_mask != -1 && (chip->codec_probe_mask & AZX_FORCE_CODEC_MASK)) { azx_bus(chip)->codec_mask = chip->codec_probe_mask & 0xff; dev_info(chip->card->dev, "codec_mask forced to 0x%x\n", (int)azx_bus(chip)->codec_mask); }
