Hi,
could you please send some more information? Output of the TRACE1("Opening ALSA device %s\n", buffer); above the snd_pcm_open would be great and also your sound card type and version will definitely help.

Hi,
I've attached the output of running AudioSystemGetLineTest against openjdk-6-src-b09-11_apr_2008 with USE_TRACE defined, and the description of my sound card reported by lspci -vv.

I updated the patch a little to make it all a bit more robust. It splits the locks, so there is no longer one gaint static one (I shouldn't have reused the lockNative one and made that static in the original patch).

This is great! Sorry for the late response. I integrated it into icedtea. But I haven't set it as default yet because I didn't have time to fully test it. I do want to have it integrated so others can play with it though. Also thanks for your AudioFloatFormatConverter.getTargetFormats() fix, I removed my own attempt of fixing that. And for integrating the dls/sf2 soundbank opening issues. Also since we now have jtreg integrated I imported all the tests so they will now all be run by default on a make check (or make jtregcheck). That found two issues. One with a test. TestRender1 accesses its test files through getResourceAsStream(), but the jtreg tag specification recommends opening files through the system property test.src so that the test can be run inside another work directory. See http://www.openjdk.org/jtreg/tag-spec.txt Patch to change this attached. The other issue is with the change that made SoftAudioProcessor (limiter, reverb, chorus, agc) more general. Since you cannot provide a Synthesizer directly to one of these classes you need a way to pass it the control rate. Unfortunately SoftSynthesizer.getControlRate() is currently protected and there is as far as I can see no other way to get the control rate. So I believe the method should be made public. A change to do this and adapt the tests to use this is attached. With these changes all tests pass.
