Upgrading or doing a clean install will leave you with alsa 1.0.21. I
did both a while back (an upgrade and a clean install to 10.0.4 from
9.10) and every single time I ended up with alsa 1.0.21. I had
previously upgraded to 1.0.22 when I was uing 9.10. I am now using
10.0.4 with the latest Alsa drivers 1.0.23. So I would suggest that you
do an upgrade to 1.0.23 if of course you deem that suitable for your
system. I did it on mine because my sound card hda-intel is better
supported in alsa 1.0.23. 

Let me know if you have any issue
