Hi, I have an ALSA sound driver working on an ARM platform running on a 2.6.10 kernel. But when I ported this driver to the 2.6.16.19 kernel it does not work. The device nodes show up, but when I try to call any of the OSS-emulation ioctls (for example, SNDCTL_DSP_SETFMT) I get a -EINVAL return code from the ioctl call and a "No usable accesses" error gets printed to the console. (I do have OSS emulation enabled in the kernel.) Has something changed with the kernel sound APIs between 2.6.10 and 2.6.16 that would cause this problem? I have reviewed the kernel ChangeLogs, but nothing pops out at me. Any suggestions would be appreciated. Thanks, -Ross _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-devel
