I don't know if you can get them on a Chapter 119 request but I do know that anyone can file a motion with any criminal court Judge seeking an Order that a transcript (which is a public record) be provided. You will be obligated to pay the costs associated therewith but you are almost certainly entitled to the Order and transcript.
First, second and third: No attorney-client relationship exists by virtue of any Q&A with Michael A. Haber, Esq. on Avvo. Fourth: Anything that you post on Avvo (or on similar sites) or on any social media is by its nature public. It is essentially an admission / confession and can be introduced into evidence as a statement against your interest in a subsequent legal proceeding. Once posted you lose any reasonable expectation of privacy, so, as this is an open forum (with no privilege attached), please be extra careful when considering what to post online (forewarned is forearmed.)
Hearing transcripts that have not been sealed by the court are public records, as are any documents in the court file that are not under seal. Anyone willing to pay for transcripts or copies can obtain them.
Chapter 119 requests seek information that is not public. The defense files are privileged and not subject to 119 requests. The SAO files cannot be obtained while there is an "open investigation" . However, once the case is closed, Chapter 119 may be used to obtain SAO and law enforcement files.
Please remember that Q & A forums such as this one are intended to provide general information, not specific legal advice upon which you should rely in making decisions about your case. Before making any such decisions regarding your case, please consult a lawyer .
In both counties the Court Reporters are not official employees of the State. They are generally third party private companies. As such, I don't think the recordings or transcripts of the recordings are subject to Chapter 119 public records requests. You can however, request and pay for, recordings from any court proceeding that has not been sealed by order of the court and pay for the costs or ask to be declared indigent for costs and then they will eventually be paid for by the State.
