SDL_AudioDeviceID. SDL Audio Device IDs. A successful call to SDL_OpenAudio( ... ) is always device id 1, and legacy SDL audio APIs assume you want this device ID. SDL_OpenAudioDevice( ... ) calls always returns devices >= 2 on success. The legacy calls are good both for backwards compatibility and when you don't care about multiple, specific, or capture devices.

SDL_PauseAudioDevice - SDL Wiki

Remarks. This function pauses and unpauses the audio callback processing for a given device. Newly-opened audio devices start in the paused state, so you must call this function with pause_on=0 after opening the specified audio device to start playing sound.This allows you to safely initialize data for your callback function after opening the audio device.

If you built your own SDL, you probably didn't have development headers for PulseAudio (or ALSA), so it's trying to use /dev/dsp, which doesn't exist on many modern Linux systems (hence, SDL_Init(SDL_INIT_AUDIO) succeeds, but no devices are found when you try to open one). "apt-get install libasound2-dev libpulse-dev" and rebuild SDL...let the configure script find the new …

Re: "SDL failed to open audio: No available audio device". Fri Apr 23, 2010 5:38 am. Kdenlive uses `aplay -l` or reads /proc/asound/pcm for lines with "playback" if no aplay available. It uses these to generate plughw:, ALSA PCMs. Then, it sends that to MLT, which sets the environment variable AUDIODEV for SDL.

Show activity on this post. I'm trying to use TravisCI to test a SDL application, which has audio functionality (but the test does not require it). When I started the app in the Travis's VM, it exited with: ALSA lib confmisc.c:768: (parse_card) cannot find card '0' ALSA lib conf.c:4241: (_snd_config_evaluate) function snd_func_card_driver ...
