OK, when and how, what?!
Would you care to give us a little more information?
You haven't given us a lot to go on here. This is Linux.org, not the psychic hotline! Ha ha!
The title of your thread tells us you're having some kind of sound-related problem on your HP Spectre running a version of Ubuntu, but we don't know any more than that.
Please try to clearly describe the problem and when it first started for you.
Was the sound working and you lost it after an update?
Or are you saying that you did a fresh install and you have no sound, and are asking if there is some kind of update to fix it?
Also, exactly which version of Ubuntu are you using?
You said "last" version.
But do you mean the "latest", or "Most recent" version?
e.g. 21.10?
Or do you mean the "last" version, as in the "previous" version?
e.g. 21.04?
Or are you using a different version of Ubuntu altogether?
Once again - the more information you can provide, the more likely it is that we'll be able to answer your question in an accurate and timely fashion.
