iMac14.2 Sound problems. Cirrus Logic CS4206

My 14.2 iMac (late 2013) is running Sequoia 15.0.1 (24A348). However, since some of the Ventura updates, I've been having sound issues. There's no option for internal speakers in the audio output—only digital out when using the default OCLP.

I installed AppleALC and tried alcid=61, 91, and 99, which made the internal speakers work, but the microphone still doesn't function. After searching for other alcids, I found that alcid=23 enables the microphone, but then there's no sound output to the internal speakers.

I looked into the layouts on GitHub for AppleALC, and my sound card (Cirrus Logic CS4206) should use alcid=18, but that doesn't work at all.

What can I do to get both the microphone and internal speakers working?
