Exactly my point: this laptop's transmitted packets are received just
fine on the other end, it's the replies that are getting missed by the
decoder so the chipset is not too badly broken, apparently.
Unfortunately, I am not really a DSP expert, so there might be deeper
reasons why the soundmodem is using a specific sample rate rather than
the one most convenient to the hardware, especially considering that
quite a few recent chipsets only offer a limited selection of rates.
B73,
Andrea.
