ALSA lib pcm.c:7339:(snd_pcm_recover) underrun occurred

When running a game in dosbox v0.74 I get many of these lines:

ALSA lib pcm.c:7339:(snd_pcm_recover) underrun occurred

and NO sound

result of `lsmod | grep snd`:

`lspci|grep Audio`:

00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 05)

I have ALSA and pulse installed, but I guess here it's only about ALSA.
My .asoundrc contains only the pcm.* stanzas for skype.

Does anybody have insight in this issue?

It's a buffer underrun, so check your buffer, while dosbox is playing sound:

cat /proc/asound/card0/pcm0p/sub0/hw_params

As an example of explicitly specifying the ALSA buffer size, here's my ~/.asoundrc

Maybe the ALSA code within dosbox should be tweaked.
