I got in touch with someone close or part of the ALSA team via
linuxquestions.org (Excellent site!). We went back and forth a bit
reaching the following conclusions and results:
- - My sound system is not explicitly supported by ALSA yet. The latest
development version just added support for a similar Toshiba notebook.
By downloading, building and installing the 1.0.14rc1 snapshot and then
explicitly specifying "model=toshiba" the new drive improved things.
- - There is still the screech in KRecord but no longer in Audacity. (Huh?)
- - Audacity recordings are clean but playback 1/2 live speed. (Huh?) By
applying a +100% speed effect, it sounds fine. Clumsy work-around but
at least it is not screaming at me there.
- - The alsamixer and therefore KMix options now make more sense to match
the hardware. Still no "mic boost" but I can disable the built-in mic,
which is a good thing.
- - Communication via Skype is now good. I have not tried other VOIP type
applications yet.
I'm going to play around more with this as I take the time and have the
need. Maybe I can do more debugging for the ALSA team to finally get it
all ironed out.
