Subject: [acrn-users] Audio Requirements for SOS & Android Guest using VirtIO

 

Hi,

I’ve been trying to sort out what is and what is not required for an SOS and Android guest configuration using VirtIO.

I am currently setup for 0.5.2 on MRB Rev E.   I was wondering if I could get some clarity from the Audio expert(s) on this topic.

·         Audio VirtIO driver stack:

o   For example: Which audio drivers should be loaded? Not loaded? (SOS and Android):

§  snd_soc_skl

§  snd_soc_tdf8532

§  snd_soc_sst_bxt_sos_tdf8532

§  snd_soc_skl_virtio_be

§  snd_soc_skl_virtio_fe

§  snd_soc_skl_ipc

§  snd_soc_sst_dsp

§  snd_hda_core          

§  snd_hda_ext_core

§  others?

·         Audio Firmware Collateral (SOS and Android):

o   Required firmware files and locations, required links, etc.

·         Misc

o   Required kernel config settings (SOS and Android):

o   launch_uos.sh modifications

§  Any other special system steps required to enable/launch the VirtIO audio service

o   etc.

Thanks in advance

Clyde
