alsa-lib 1.1.1 发布了，Advanced Linux Sound Architecture (ALSA) 为 Linux 系统提供了统一的音频和MIDI功能和驱动。 相关改进信息： Core Release v1.1.1 Define some types if missing Define EBADFD in terms of EBADF if it doesn't exist. Control API control: keep consistent usage of assertion control: initialize element channel values according to identification number at adding a new element control: fulfill a description about element type with integer64 coverity fixes control: add missing asserts to ctl_elem_set functions PCM API pcm: fix 'unable to create IPC shm instance' caused by fork from a thread Introduce bswap.h for portable definitions of byte swap macros. coverity fixes pcm_hw: fix possible memory leak (coverity) pcm: simple: Fix asserts Sequencer API seq: Provide sequencer sound card number / PID via alsa-lib Timer API Only use F_SETSIG fcntl where it exists. Topology API topology: Add support for widget byte controls topology: add support for CTL access flags to config file topology: add support for pasring external ops in conf files topology: Add ops to bytes control. topology: Remove unnecessary includes topology: fix debug output to print correct "max" value. topology: Quit and show error message on big-endian machines topology: Not compare a for loop iterator with ABI __le32 variables topology: Fix comparison of unsigned expression < 0 topology: Remove unused variables topology: Remove unused function write_data_block() topology: open topology files with O_TRUNC topology: Add missing include sys/stat.h 下载地址：ftp://ftp.alsa-project.org/pub/lib/alsa-lib-1.1.1.tar.bz2 ALSA-Lib 1.1.1 发布，音频和MIDI功能驱动下载地址
