command-line-based toolsets, such as mixer (mixer), audio file player (Aplay), and tools to control specific properties of specific sound cards.ALSA ArchitectureThe ALSA API can be decomposed into several main interfaces:1 Control Interface: Provides common functionality for managing the sound card registration and requesting available devices2 PCM Interface: manages digital audio playback (playback) and recording (capture) interfaces. The following summary of this article focuses on this inter

it as. dosbox. conf, you can enter the following command when starting dosbox to make it take effect.
Dosbox-conf ~ /. Dosbox. conf
Configure the sound Device
When you use dosbox to play a game, you may see the following prompt:
ALSA: Can't subscribe to MIDI port (65: 0) MIDI: Opened device: oss
This indicates that the default device is alsa, but alsa does not support
h1 := 0xEFCDAB89var int h2 := 0x98BADCFEvar int h3 := 0x10325476
If you find these four constants in a row of the Code, it is very likely that the function is related to MD5.
Another example of the CRC16/CRC32 algorithm is usually calculated using a pre-calculated table:
/** CRC table for the CRC-16. The poly is 0x8005 (x^16 + x^15 + x^2 + 1) */u16 const crc16_table[256] = { 0x0000, 0xC0C1, 0xC181, 0x0140, 0xC301, 0x03C0, 0x0280, 0xC241, 0xC601, 0x06C0, 0x0780, 0xC741, 0x0500, 0xC

2. Midi, short for Musical Instrument Digital Interface, is also known as the digital interface of musical instruments. It is a unified international standard for digital music/electronic synthesis instruments. It defines how computer music programs, digital synthesizer, and other electronic devices exchange Music signals, it specifies the protocol for data transmission between cables and hardware and equipment connected by different manufacturers

List all files and specific subdirectories (if the subdirectory contains a. nomedia hidden file, it will not be listed .). The listed file is used to determine whether the file is supported based on the file extension. If this file extension is supported, the C ++ layer calls back to the Java layer to scan the file. This extension will be scanned and listed in mediafile. java. The following is a list of supported file extensions.
