AppleALC Kext 1.4.3 Intermittent Corrupted Audio

[calbear92]

Just noticed that on XPS 9570 Catalina Build 10.15.2 that after updating to Apple ALC kext 1.4.5 that the audio would intermittently warble together. Ugh again.

[Had similar issues on 10.15.1 with 1.4.3
Downgraded to 1.4.0- better, but still less frequent chop.

1.3.9 also had some rare chop.

Installed 1.4.2=5. So far so good.]

我的10.15.1下 睡眠唤醒后耳机没有声音 并且热拔插type-c也不可用

[calbear92]

went back down to 1.4.0 and used ID=72. So far so good.

[calbear92]

updated to 1.4.4 and Clover 5099: so far so good.

[xyhs2018]

which os version using now,10.14.6 or 10.15.1?

[calbear92]

10.14.6. I had too many overall performance drags with Catalina so I down-graded back to Mojave.

[xyhs2018]

ALCPlugFIx will help you.
Download it from https://github.com/jardenliu/ALC298PlugFix.
If you're using 10.15.1, you must use this command �first sudo mount -uw /
Extract and run install.sh file with sh ./install.sh
It working properly with me. Good luck!

Updated to Clover 5100 and updated to AppleALC Kext 1.4.5: 99% good.

[jaromeyer]

not really related to this, but @xyhs2018 were you also required to do the tape mod to get the dw1820a working at all? and what speeds are you seeing?

[calbear92]

updated to Clover 5103, AppleALC Kext 1.4.5. Working 99%.

updated to Clover 5118, AppleALC Kext 1.5.0, macOS Catalina 10.15.5! After a lot of try and error I figured out using layout-id 28 to have sound and microphone working:
<key>PciRoot(0)/Pci(0x1f,3)</key> <dict> <key>AAPL,slot-name</key> <string>Built-in</string> <key>device_type</key> <string>Audio Controller</string> <key>layout-id</key> <integer>28</integer> <key>model</key> <string>Realtek ALC298</string> </dict>

above mentioned layout id 72 also works with microphone and internal speaker. I did not test it with HDMI audio out
