Wiped out W7, now have antiX 13.2 on and machine runs like a champ! Only real problem is sound--or rather, lack of same. Have futzed around for a while, and sort of know what the problem is. First, here are the sound specs:

Code: Select all

jb@BondAcer2:~
$ cat /proc/asound/modules
 0 snd_hda_intel
 1 snd_hda_intel
jb@BondAcer2:~
$ lsusb
Bus 002 Device 003: ID 064e:d214 Suyin Corp. 
Bus 003 Device 002: ID 0a5c:2198 Broadcom Corp. 
Bus 003 Device 003: ID 192f:0416 Avago Technologies, Pte. 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
jb@BondAcer2:~
$ cat /proc/asound/cards
 0 [Generic        ]: HDA-Intel - HD-Audio Generic
                      HD-Audio Generic at 0xf0444000 irq 41
 1 [SB             ]: HDA-Intel - HDA ATI SB
                      HDA ATI SB at 0xf0440000 irq 16
I installed VLC, and using that can switch to the second card, which then works fine. But I can't figure out how to reverse the order system-wide. Don't actually understand what the generic card is there for in the first place, so don't want to just black list it.

Thoughts? TIA

OK, got it after searching around some more:
  • find card numbers with

    Code: Select all

    $ cat /proc/asound/cards
  • create a file in home directory

    Code: Select all

    .asoundrc
  • open new file and paste in

    Code: Select all

    pcm.!default {
    type hw
    card 1
}

ctl.!default {
    type hw           
    card 1
}
  • use the card number that you want to be default
  • reboot
Woot!

I'm sure there are others here who know more about this stuff than I do.

indicates there is an hdmi sound output and an non-hdmi sound output which makes sense.

gives instructions for selecting the sound card system-wide. Their first method seems to assume the different cards use different sound drivers (modules). The Alternative method, using ~/.asoundrc or / etc/asound.conf does not make this assumption. It says you just need to add something like the following to your ~/.asoundrc file:

Code: Select all

pcm.!default {
    type hw
    card 2
}

ctl.!default {
    type hw           
    card 2
}
BTW: the output if"lspci -k" might have been more useful than the output of"lsusb" but since your system was already in the database I linked to above, your lspci output was not needed.

Thanks for looking. I used that Archlinux page myself in posting the answer above, which I guess you did not see (?).

Yes, I missed your second post. I sometimes get distracted by higher priorities and finish a reply long after I started it.
