Re: [Alsa-user] Playback problem arised with alsa-lib-1.0.14rc4 and ladspa plugin
Hello Garnet, Am Montag, 30. Juli 2007 21:58:05 schrieb Garnet MacPhee: Hi, Benjamin, I saw your post on the alsa-user forum, and it seems to me that the problem you are having is the same as mine. I posted on June 22, my post was titled ttable for ICE1712 not working in alsa-lib 1.0.14a. There apppears to have been a change in alsa-lib between release 1.0.14rc3 and 1.0.14rc4 that is causing our problem. I have not been able to resolve it yet, so I am still running alsa-lib at 1.0.14rc3. I am currently running the alsa driver at 1.0.14, but it seems to not matter what release the driver is. I collected some of the same documentation that you did in your post. Let me know if you have made any progress on this, and I will do the same. Garnet MacPhee I just tested alsa-lib version 1.0.15rc1. In this version I do not have the problem anymore. The changelog lists the fix of the float plugin too.

Dear alsa-user list members, I still have no solution to my problem. Maybe you do not know either what to do. But maybe you can give me a hint or tell me how I could debug this problem. Or do you think that I should contact the alsa-devel mailing list? Maybe that is a better place for this kind of problem?
