Fix for HD-audio beep error
Fix for ice1724 ctl error |
||
Hi On Manjaro I have the same problem with kernel 5.6.1 and 5.6.2 (5.6.0 worked fine). My soundcard uses the snd_ice1724 driver and during boot I get this error message: kernel: snd_ice1724 0000:04:00.0: control 2:0:0:Analog Capture Source:0: access overflow Alsamixer can no longer open this soundcard. I still get sound but I have to raise the volume much higher in Pulseaudio (as it probably can not raise the hardware volume). You can disable the control element check - CONFIG_SND_CTL_VALIDATION kernel configuration. Takashi? Driver issues? But I don't see any problem in ice1724 / prodigy_hifi.c - wm_adc_mux_* functions. Recompiled the Manjaro 5.6.2 kernel with CONFIG_SND_CTL_VALIDATION=n and everything is working again as expected.

Fix for ice1724 ctl error
(In reply to Takashi Iwai from comment #4) > (In reply to Matthew from comment #0) > This one is indeed a bug but rather harmless one. The fix patch is below. The beep error wasn't the bug. I had no sound at all. That's simply the only error message the kernel gave me. I meant the access pattern in HD-audio wasn't a real bug but it's treated as if a real error by the validator. In anyway, please try the patch. I use Arch too and I also have no sound. I also get the error in dmesg: [ 1545.634891] snd_hda_intel 0000:00:1b.0: control 2:0:0:Beep Playback Switch:0: access overflow Is there a workaround because I have no idea how to apply the patch and also dont have resources to do that. (very slow system) At best ask your distributor to provide a patched test kernel. (In reply to Takashi Iwai from comment #5) > Created attachment 288239 [details] > Fix for HD-audio beep error Kernel compiled and this patch appears to solve the no sound issue. Thank you kindly! Thanks for confirmation! The patches have been merged to sound git tree, and will be included in the next pull request to Linus for 5.7-rc1, then they'll be backported to stable branches.

To be clear, I did not test the ice1724 patch, only the hd-audio patch. I cannot confirm whether the other patch functions as expected as I do not use that sound card. I applied both patches to Manjaros 5.6.3 kernel and my ESI Prodigy 7.1 HiFi card is working again. The CONFIG_SND_CTL_VALIDATION variable is now unconfigured in Manjaros default kernel, so i will recompile the kernel again with this variable set to yes to see if everything will still work. OK - Everything is still working with CONFIG_SND_CTL_VALIDATION=y Thanks @Takashi for the quick fix. |
Running Arch Linux distro, upgraded kernel to testing release linux-5.6.2-arch2-1. After rebooting, there was no sound. I checked the system journal and it showed these errors: pulseaudio[904]: W: [pulseaudio] alsa-util.c: Unable to load mixer: Invalid argument kernel: snd_hda_intel 0000:00:1b.0: control 2:0:0:Beep Playback Switch:0: access overflow Downgrading kernel to 5.5.13 resolved the issue and I once again was able to play sound. Audio device is: 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05) Subsystem: Dell 6 Series/C200 Series Chipset Family High Definition Audio Controller Kernel driver in use: snd_hda_intel Kernel modules: snd_hda_intel If any more information is required I am happy to provide it, I'm just not sure what is relevant and what isn't at this point.
