I am trying to convert some old cassette music to audio

format. I'm very new to Linux audio, mixers, and so forth,
and have some newbie-type questions to ask.
I'm running the 2.2.14 kernel with the ALSA drivers, version
5.12a, es1968 module, with an es 1978S soundcard. The problem I
have is that I get a loud, persistent, evenly-spaced clicking
sound in my input.
I have tried running ecasound with "-r -z:nointbuf", but that
doesn't seem to help.
I'm not familiar with the -z:nointbuf but I've had exactly the same noise as you
described and I was able to get rid of it with the -b option.
It was tricky though. I stared with -b:64 (didn't work), then I doubled to -b:128
(didn't work). To make a long story short, after doubling for a while, I ended up
dropping the number by 100, then by 50... until I narrowed it down to the _exact_ buffer
size that stopped the clicking.
It may be different for you, but I think the number that worked for me (at the time) was
-b:150.
BTW, they say that the -b option works best with even numbers.
