Welcome! Yes you may post your questions here, just as you posted the last one.
Regarding your two sentences:
1.............she sounded like very sad.
2..............she was sounded like very sad.
To say what you want to say about your sad friend, you would say, "She sounded very sad."
To 'sound like' means to make a sound that is the same as (something else):
'She sounds like her mother. On the telephone I can't tell who is speaking.'
I hope this is helpful,
