There are three ultimate propositions in Philosophy: Who are you? From where? Where to go? For the dapm mechanism, we can ask: What is dapm and what is its function? How is dapm created? How is dapm triggered? The following is an analysis of these three problems. First, what is dapm? This is mentioned in the overview of dapm, that is, the dynamic management of audio power supply. I believe that power management is not unfamiliar to everyone. The purpose of the dapm design is to enable the necess

transparent to all user space applicationsAll power switching is done within the ASOC core. No code changes orRecompiling are required for user space applications. dapm makes powerSwitching decisions based upon any audio stream (capture/playback)Activity and Audio Mixer settings within the device. Dapm spans the whole machine. It covers power control within the entireAudio Subsystem, this includes des internal codec power blocks and MachineLevel Powe

used in Ubuntu to do this work using other programming programs. Rhythmbox (0.20.): This version will appear on Ubuntu 10.10, but now you want to use it on Ubuntu 10.04. The biggest difference is that rhythmbox has a new example, which is no longer as simple as before, now you can see her white and beautiful speakers in this version. Another reason is that the DAAP external token must be updated to use libdmapsharing, which is not yet integrated. Therefore, DAAP may not be used currently.Suppor

Broadly speaking, there are 3 major architectures in the industry: MPC, MPlayer and VLC. These 3 large architectures and their derivatives occupy 90% of the market, and none of the free media-play software that users can see comes from these 3

There are many ways to simulate a windows style tab on the webpage. Here we will introduce a simple method-using htc components.The advantage of using htc is that it can be freely called and is a bit batch-processed. For example, if you want to use this tab on many webpages, you only need to create an htc, then they are called separately on different web pages without having to make them again. It is easy to use and saves a lot of time.The procedure is as follows:1. Download

In Windows, you can add the Buffer Queue to set the buffer. ALSA does not provide the interface for you to set the buffer at the application layer, the role of the buffer zone is to weaken or eliminate the impact of occasional fast or slow data streams or user operations. Therefore, ALSA must have a buffer zone, is the hardware buffer sol
