Yes, I have the same problem on my new laptop, have to unmute and raise the level in the "Speaker" slider in Retrovol. So, pemasu's fix seems appropriate to me.
I have inserted the new line into line 60 of /etc/init.d/10alsa.
I see also that 01micko has suggested some changes also, but there doesn't seem to be any feedback on that.
Note, the fact that I have picked up this fix on page 19 of the Puppy Exprimo thread does not mean that I have read all the pages of that thread! I just followed a link into it from somewhere, oh, yeah, I was looking for something don570 posted there. So, there might be other relevant fixes buried there that I should know about?

Yeah, that will probably fix very quiet sound om some EEE hardware too.
I have another that fixes my nvidia hardware.
set 'Master Front' 75% unmute
set 'Master Front' -12dB
Note that Slacko uses a very hacked 10alsa script because alsaequal and the CAPS ladspa plugin are used for Pequalizer, a system wide alsa equalizer which zigbert and myself developed a gtkdialog gui.
Off topic, just to save a post, there is a bug in the init script with booting from mmcblk1p1 (internal SD cards , not EEE 701 though as it's on USB bus).. on the OLPC, boots fine from USB though. I haven't fixed it yet but will take a look.

scratch XO comment
... for now. Mavrothal has changed something which he thinks borks booting from internal SD

There is another 'feature' that seems to crop up from time to time in various derivatives: Retrovol does not appear in the menu. Mostly it can be activated from right-click on the tray icon. I have reported this; developers usually fix it, but it re-appears again sometime later, some version later, which suggests there might be another fundamental issue?

Long term sound problems
Hi Barry, on many versions of linux I have had this problem of low or no sound. So far it has always been down to low volume or 0 volume on mixers. Often the mixer control I need is not shown until added. For a newbie this could be a real pain.
Perhaps at initial boot we could offer up the full mixer with all control present and a little sound playing?

No, should not be the frontend_d change.
Most likely you need to change the olpc.fth because there PDEV1 is defined as mmcblk1p1.

Dpup Exprimo fixes
I believe Iguleder has already posted most significant fixes needed for woof. For building Dpup Exprimo and needed hacks and fixes I have posted as list in Dpup Exprimo first page. Muted sound problem arise when I and stu90 tried to get sound unmuted during 18.104.22.168 kernel experiments.
01micko posted his addition and I remembered my addition and posted it.
I have difficult hw in my Acer 5820TG laptop and i wasnt sure how generic my fix was. So...I havent been active to post it publicly.
