[Pkg-alsa-devel] Bug#659627: libasound2: stuttering audio due to continuous underruns

[Mario 'BitKoenig' Holbe]

Package: libasound2                      
Version: 1.0.25-2

Hello,

upgrading libasound2 to 1.0.25-2 leads to stuttering audio when playing
TV via xawtv (3.102-3) and xawtv continuously reporting
	ALSA lib pcm.c:7339:(snd_pcm_recover) underrun occurred
while reading from hw:1,0 (32KHz Bt87x Digital capture device of a Bt878
TV card, driven by snd_bt87x).
Downgrading to 1.0.24.1-4 solves this issue.


Furthermore in conjunction with pulseaudio I noticed with 1.0.25-2
alsamixer shows the normal card0 mixers while with 1.0.24.1-4 it did
show the PulseAudio mixer. I don't know if those both symptoms are
connected. According to changelog.Debian the latter could be
intentional, but IMHO libasound2 should then break old/current
pulseaudio versions to enforce coordinated upgrades.
If you think those both issues should be treated separately, please feel
free to clone this bug.


Thanks for your work & best regards
   Mario
