2023-09-04mixer: add support for pcm device specific mixer controlsRohit kumar
Mixer control such as "Playback channel map" can be registered by multiple pcm device nodes and is distinguished by device in snd_ctl_elem_id. Add support to get the control handle associated with mixer ctl name and device number. Also, introduce API to get the device number associated with specific mixer_ctl handle.

Since the variables are snd_pcm_uframes_t and snd_pcm_uframes_t is unsigned long, using unsigned int causes problem when running on a 64-bit binary. Also fix the branch name of googletest.

mixer: fix index underflow when index=0
2021-11-02mixer: fix index underflow when index=0Caleb Connolly
In mixer_get_ctl_by_name_and_index(), the post-fix decrement means that the index will be decremented after the comparison, but before the return, leading to an unsigned integer underflow. This causes a crash on platforms with -fsanitize=integer enabled. Fix this by avoiding decrementing index until after the return. Change-Id: I25a17ced4185bdebd500285bd30b342b16b4ac12

force pcm_open to open device with the non-blocking flag
2021-06-02force pcm_open to open device with the non-blocking flagdvdli
When a client opens a PCM device whose substreams are all occupied without the non-blocking flag, the open function would be blocked in the kernel until the previous opened ones are closed. This would cause deadlock if they try to hold the same lock. Most of the ALSA PCM drivers on embedded systems are implemented with the ALSA SOC framework. Each PCM device has only one substream. This problem would happen frequently. To force pcm_open to open PCM devices with non-blocking flag is beneficial to resolve this problem. It returns the control to clients to try again later. The reason why we don't call pcm_open with PCM_NONBLOCK is that the PCM_NONBLOCK also affects the read and write behaviors. I also add a test case to test whether the pcm_open would be blocked.
