When I update to 6.17 (from 6.16) kernel the audio stops working on my 2019 iMac desktop. This isn’t the first time - actually, it’s the usual dance I have to do since the fix is to re-run the `snd-hda-codec-cs8409` patch. [Which can be found: [here](https://github.com/egorenar/snd-hda-codec-cs8409).] In the past it all works out eventually - after multiple attempts. But not this time. I’ve used `timeshift` several times again to return to 6.16, which immediately resolves the audio problem. But I can’t be stuck with 6.16 forever, So… The problem seems to be that when I try to `make` (before invoking `sudo make install`) the patch I get a Type 2 ERROR and I can’t seem to figure out quite why. Below is what appears on the screen when running `make`. Any additional logs needed for insight? (If so, where might I find them?) ```auto [ejm@iMac-i3 snd-hda-codec-cs8409]$ make make -C /lib/modules/6.17.5-zen1-1-zen/build CFLAGS_MODULE="-DAPPLE_PINSENSE_FIXUP -DAPPLE_CODECS -DCONFIG_SND_HDA_RECONFIG=1 -Wno-unused-variable -Wno-unused-function" M=/home/ejm/snd-hda-codec-cs8409 modules make[1]: Entering directory '/usr/lib/modules/6.17.5-zen1-1-zen/build' make[2]: Entering directory '/home/ejm/snd-hda-codec-cs8409' CC [M] patch_cs8409.o patch_cs8409.c:1083:10: error: ‘const struct hda_codec_ops’ has no member named ‘free’ 1083 | .free = cs8409_free, | ^~~~ patch_cs8409.c:1083:17: error: initialization of ‘void (*)(struct hda_codec *, unsigned int)’ from incompatible pointer type ‘void (*)(struct hda_codec *)’ [-Wincompatible-pointer-types] 1083 | .free = cs8409_free, | ^ ~~~~~~~~~~ patch_cs8409.c:1083:17: note: (near initialization for ‘cs8409_cs42l42_patch_ops.unsol_event’) patch_cs8409.c:957:13: note: ‘cs8409_free’ declared here 957 | static void cs8409_free(struct hda_codec *codec) | ^ ~~~~~~~~~~ patch_cs8409.c: In function ‘cs8409_cs42l42_fixups’: patch_cs8409.c:1137:22: error: ‘struct hda_codec’ has no member named ‘patch_ops’ 1137 | codec->patch_ops = cs8409_cs42l42_patch_ops;

I would use the LTS kernel instead of an unsopported EOL 16.6 kernel series. ---

Thank you for your prompt followup. The LTS (6.12.55-1-lts) definitely works (that is, after running the `make` and `sudo make install` on the audio patch). And so does the 6.16 series beyond that, which is what I’ve been using until now. I guess my concern is that if I can’t get it to work properly on the 6.17 kernel, at some point when that series becomes the new LTS, I’ll be stuck. Feels like I’d just be kicking the proverbial can down the road? ---

Greatly appreciate your pointing me to the github site again. I had checked when I first experienced this several weeks back but there was no traffic on this topic so I didn’t bother - figured it was something foolish just at my end. Now there are others, so I’ve added a brief comment too. Hopefully this gets resolved sometime before Dec 2026 🙏 ---

@Merlin1 Thanks for this info. For the sake of completeness, when I have had success in continuing to use the snd patch (for several years’ worth of kernel upgrades) it’s been thanks to following this guidance from here… Perhaps this will be helpful to someone down the road: > **[No Sound on iMac 5k (iMac 19.1) ''27 2019](https://forum.manjaro.org/t/no-sound-on-imac-5k-imac-19-1-27-2019/111631/15)** > > I had the same issue for a long time, and solved it yesterday by install the Sound Driver for Cirrus Logic CS8409 for iMac27-5k from github. get the kernel version:uname -r Install package linux-headers, select the same version with kernel... For now, I’m stuck using the LTS - which isn’t a bad outcome, just not my preference. ---
