I thought a lot about .asoundrc syntax and I strongly believe the language/syntax simply has no right to exist in a sense. I mean, a language like Perl, Python, Ruby can adequately describe what .asoundrc does, so if instead of .asoundrc syntax we use one of the languages above, we, at least, have a well established parser which, luckily, reports user syntax errors. Not using an existing language normally causes half-hearted parsers to be written in possibly QND manner. I witnessed excessive language invention a lot in my career; replacing the unnecessarily invented languages with well established ones was the key factor in solving the problems. The semantic check shouldn't be that hard to write, so semantic errors would be reported too. The good news is that, say, Perl (I'm in favor of Perl) has Inline.pm module, which allows to relatively easy call anything written in C/C++, as well as other languages. The bad/unknown news is that I do not know whether ALSA has a well documented HAL and API to it. I mean, the realization of user configuration would mean first querying HAL/it API in order to find out whether the requested functionality is supported by the card(s), and then calling ALSA lib routines to implement the requested functionality. I would be interested to read documentation on ALSA HAL+API - if the one exists. ------------------------------------------------------- Using Tomcat but need to do more?
