Porteus

Thanks to some handholding by fanthom I have now got an ATI driver for my Acer AO722. Details at:
( http://forum.porteus.org/viewtopic.php? ... c&start=10 )

Unfortunately, sound is still not working correctly.

I am running Porteus 1.0 64bit on an Acer Aspire One 722.

Symptoms:
KDE boot sound and audible notifications work correctly.
VLC gives an error message (cannot initialize sound card) but plays properly.
SMPlayer accesses files and seems to be playing but no sound is present.
Online players (shoutcast, youtube) think they are playing but no sound. If I direct shoutcast output through VLC, it plays properly.

I suspect there is something going on with phonon and/or PCM but don't know

As requested:

Output of cat /proc/asound/cards:
0 [Generic ]: HDA-Intel - HD-Audio Generic
HD-Audio Generic at 0x90444000 irq 40
1 [SB ]: HDA-Intel - HDA ATI SB
HDA ATI SB at 0x90440000 irq 16

Thanks for any advice.

Posted after 3 hours 59 minutes 50 seconds:
An update on this. After lengthy experimentation and internet search I have found that adding a .asoundrc file to my home directory enables proper audio playback. The contents, given below, allow all playback (smplayer, vlc, from internet) to work properly. This file works with the out of the box porteus base, without the fglrx driver being added separately, on my system at least (Acer A0-722, porteus 1.0 64 bit).

I am now struggling with getting the microphone to work, but will ask my question in an alsa thread.

Many thanks for everyone's assistance.

Best regards,

good that it's working for you

for future reference: the best method in dealing with priority for 2 (or more) sound cards would be to use asoundconf package from AUR (Arch User Repository)
http://aur.archlinux.org/packages/asoun ... onf.tar.gz
download it and unpack, then edit 'asoundconf' and change first line from
#!/usr/bin/python2
to
#!/usr/bin/python
you can use it with following syntax: this script gonna create .asoundrc.asoundconf config in your home directory so in case of not saving changes you need to copy it to /porteus/rootcopy/<home_dir> folder

please add [SOLVED] to the thread title.
