> To get a grasp of what PIE sounded, the closest you can get in Europe is by listening to Lithuanian

No you can’t. Especially not the “sounded” aspect. Lithuanian is conservative in some matters of lexicon and morphology, but modern Baltic phonology is very different from PIE. The ancestral stages of Lithuanian after PIE lost the PIE laryngeal sounds, then the distinction of three classes of velars and aspirated/non-aspirated stops, and in more recent centuries there has been some palatalization processes and loss of nasal vowels (though the latter are still denoted in writing). The developments in Baltic-Slavic tone after PIE are also an infamous mess.

All in all, when you listen to Lithuanian, you are listening to just any IE language instead of gaining special insights into PIE.
