It plays normally, but when I click the arrows to advance in the music, I noticed it have a delay, and it lags if I click like 3 times to advance. And if click to close the application, the application close in the same time, but the audio stay playing for a while. The next thing is mplayer, It lag to advance the video (as cmus), but it don't stay playing when I click close. How long is the lag? It's about 1.5 - 2 seconds. This really sucks I need to advance the music and click more than once. By default the buffer size is large which causes around 0.2 second of extra lag but makes audio stable (this is to allow audio to kinda work on busy or on MP systems). You could try to use smaller buffers, for instance add: sndiod_flags=-z 480 to /etc/rc.conf.local and restart sndiod with: /etc/rc.d/sndiod restart This didn't solved, maybe the audio is a little faster, but continue more than 1 sec of delay. -- Regards Henrique Lengler -- Regards Henrique Lengler

It plays normally, but when I click the arrows to advance in the music, I noticed it have a delay, and it lags if I click like 3 times to advance. And if click to close the application, the application close in the same time, but the audio stay playing for a while. The next thing is mplayer, It lag to advance the video (as cmus), but it don't stay playing when I click close. How long is the lag? It's about 1.5 - 2 seconds. This really sucks I need to advance the music and click more than once. By default the buffer size is large which causes around 0.2 second of extra lag but makes audio stable (this is to allow audio to kinda work on busy or on MP systems). You could try to use smaller buffers, for instance add: sndiod_flags=-z 480 to /etc/rc.conf.local and restart sndiod with: /etc/rc.d/sndiod restart This didn't solved, maybe the audio is a little faster, but continue more than 1 sec of delay. -- Regards Henrique Lengler

The last similar problem happens when I am playing a html5 video and I pause or it stops to load, the audio gets desynchronized.

Audio probles like, slow response in applications that use audio and a little noise in the background
Hi, I'm new in OpenBSD (I'm loving it), I came from Linux. I installed the last (5.6) version, and I started to use, without doing any change in audio settings.

All these errors happens on the console too. My keyboard normal keys have no lag in Xorg (I have lag problems in Caps/Num/Scroll Lock keys under X, but this is for another post). ** Now the hardware/software info: ** My motherboard is a ASUS Z87-K, the official site says it have an Realtek ALC887 8-Channel High Definition Audio CODEC *2 audio device.
