Hello,
My laptop (LG Gram Style 14; ALC298) does not have sound on linux which most likely seems to be the AMP not being turned on.
I could not get it up with hda-analyser and other means so the last option was to dump CORBs from a windows VM and replay them on linux.
I have been able to generate an output by enabling tracing in qemu and also applying a patch to capture 'hidden' CORB writes by Joshua Stein (https://jcs.org/2018/11/12/vfio).
However, so far I have been unsuccessful in extracting the verbs from this dump or frames (I am not sure what that is) as the QemuHDADump repo (and forks) mention.
The output from these tools is just filled with 0s and there are no frame files created.
The tools used for extraction: https://github.com/Conmanx360/QemuHDADump, https://github.com/abridgewater/QemuHDADump
Details about the audio device can be found here: https://bbs.archlinux.org/viewtopic.php?id=290994
The CORB dump from Qemu: https://bugzilla.kernel.org/attachment.cgi?id=305973
Thank you.
