That command tells you that libasound2-dev is _available_ in the package
repository, it does not tell you if it is installed. You can use dpkg to
$ dpkg -l libasound2-dev

IIRC that was a change in ALSA default behavior: Back in the day ALSA
provided an OSS compatible interface by default, but nowadays this is
disabled by default. Using the ALSA driver should give better results
than using the OSS driver with ALSA's compatibility layer (if you find
out how to enable it).
Bufferbloat just waits in hiding to get you when you try to use the network.
