Thanks Tanu. > pacmd doesn't work with the system mode, but that's not a problem, just > use pactl instead. pactl is better than pacmd anyway. > If you stop pulseaudio, does "aplay -Dplughw:0,0 test.wav" work? If it > doesn't, it's probably an alsa problem. "pactl" works well. But when I stop pulseaudio and use "aplay -Dplughw:0,0 xxx.wav", it just a little short voice: "Playing WAVE 'VoiceFile/filem.wav' : Signed 16 bit Little Endian, Rate 8000 Hz, Mono" It seems that aplay use a wrong format to play that. Also, I'm using Qt to make a the project (e.g QSound, QSoundEffect are based on pulseaudio) and I want to play different audio files at the same time.But there are some problem 1. I found the voice had "electricity-noise"( I hope you can understand it :) ) when different QSoundEffects paly different files 2. The volume is mismatching(e.g. QSoundEffect volume is from 0.0~1.0 , when I set more than 0.1 , the voice is changed to be biggest) 3. When I play one audio file in loop with different volume in each time by QSoundEffect, the latest voice will remain a little last time voice How to solve these problem? I have also reported them to Qt. -- Regards Mihan _______________________________________________ pulseaudio-discuss mailing list pulseaudio-discuss@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss
