(Solved) LXDE 2012.6 Live CD Gmixer broken

[cncman]

Hi all,

I've been playing around with the newest LXDE live CD to see if I want to make the switch from the increasingly resource hungry KDE4. The only real issue I have is that (like all Linux Distros) my video card's HDMI port is automatically set as the primary sound output dev. I looked in the menu and found Gmixer but it wouldn't open. So I tried in LXTerminal and got:

[guest@localhost ~]$ gmixer
** Message: pygobject_register_sinkfunc is deprecated (GstObject)
W:Failed to load icon Icon 'stock_line_in' not present in theme
Traceback (most recent call last):
  File "/usr/bin/gmixer", line 1168, in <module>
    GMixer(options.daemon, options.custom_mixer_cmd, options.pixmap)
  File "/usr/bin/gmixer", line 640, in __init__
    self._build_gvolumes()
  File "/usr/bin/gmixer", line 1013, in _build_gvolumes
    sep.hide()
UnboundLocalError: local variable 'sep' referenced before assignment

I searched the forums and saw people like Volumeicon but in LXTerminal:

[guest@localhost ~]$ volumeicon
volumeicon: alsa_backend.c:88: asound_get_volume: Assertion `m_elem != ((void *)0)' failed.
Aborted

I can use alsamixer to change the volume settings on whichever device i choose, but I don't know how to select my desired card as primary output without blacklisting the snd_hda_intel driver. That requires a reboot which is pointless on a live CD.

My basic questions:
1) Are Gmixer and Volumeicon broken on live CD or is there something about my hardware they don't like?

2) If do a full HDD install of LXDE will the sound problem persist and make me wish I hadn't dumped KDE?

Thanks

Instead of a "full install" you could try "task-lxde" in synaptic.  This will allow you to boot into lxde any time, without removing kde, and you will have access to your favorite kde apps.

OK, Got sound working from the live CD:

PCC>Hardware>Sound Configuration: left the settings for the card I want (aureal vortex) alone.
Set the driver for my Radeon HD's HDMI port to "unknown." Then...
PCC>System>Manage System Services>alsa [STOP]
Then...

Code: [Select]

[guest@localhost ~]$ su
Password:
[root@localhost guest]# alsaconf
Finally..

Code: [Select]

[guest@localhost ~]$ alsamixer
Made sure no outputs were muted and volume set to something reasonable.
Voila`! Sound.

  Hadn't had to pull out alsaconf since PCLOS 0.92

Gmixer is still broken. I did find this one thread over a year old http://www.pclinuxos.com/forum/index.php/topic,94206.0.html

Just had a break through as I was writing this up. I have to reboot into a clean Live CD environment and verify. BRB!

can't replay your problem sorry, here works all fine...

Alright,

Gmixer and Volumeicon work for me from the live CD now.

Apparently:

PCC>Hardware>Sound Configuration: left the settings for the card I want (aureal vortex) alone.
Set the driver for my Radeon HD's HDMI port to "unknown."

is all I needed to do.
Funny, this is the first thing I tried the very first time I booted up the Live CD, but it didn't work then.

I guess Gmixer either doesn't know what to do with 2 sound cards or it doesn't like the snd_hda_intel driver.

Maybe you should install pulseaudio...

I like to hear you find a solution
