Description

On Ubuntu 13.04 (64 bit), after upgrading Audacious to version 3.4 from WebUpd8 ppa, with ALSA output I cannot obtain gapless playing anymore: a gap appears now at the end of every track.
I also noticed that the larger is the buffer, the more the gap's lenght increases. With the default buffer of 500 ms the gap is about a second or less; with greater buffers, it's about several seconds.
Switching to PulseAudio output, the issue disappears at all! With Audacious 3.3.* all worked fine.

I created a bug on Launchpad:

Thank you for this great software, and thank you in advance for the help!

Are you actually using ALSA or simply playing through PulseAudio's ALSA sink?

#2 Updated by Luca Rossetto Casel over 11 years ago

ALSA, with output to the soundcard. Thank you for answering!

#3 Updated by John Lindgren over 11 years ago

Through dmix, or direct to the hw: device?

What format of audio files are you playing, and does the same problem appear with other formats?

#4 Updated by John Lindgren over 11 years ago

Do both songs have the same number of channels and the same sample rate? Do you have any effect plugins enabled?

#5 Updated by Luca Rossetto Casel over 11 years ago

I set Audacious to send the sound directly to the hw: device, without passing by dmix; but I tried to use dmix too, and the problem remained.
I use Audacious prevalently as a CD player, but I made some test with other formats, with different sample rates, etc.: I could notice no differences, the bug remained.

As a further test, I tried to send the signal to ALSA through Jack: the gap is considerably reduced, nearly unnoticeable, but still present.

Dear John, I'm very embarrassed: I'm struggling to install from the source code you upload in Git, but I don't know how to do! I read some how-to, but it seems I'm missing something... Would it be possible to apply the patch to my installation of Audacious?
I humbly beg pardon!

No need to be embarrassed; compiling Audacious from source is daunting the first time. Did you try the instructions at http://redmine.audacious-media-player.org/boards/1/topics/788? Please reply to that forum post if you still have trouble.

Dear John, thank you for your patience! With your instructions, I've now compiled Audacious. Your patch resolved the bug, now everything is perfect! Thanks!!!
