<PRE>On 2012/05/05 17:05 (GMT+0100) Colin Guthrie composed:

[alsa.card_name = &quot;Intel ICH5&quot;
...
alsa.driver_name = &quot;snd_intel8x0&quot;
...
device.product.name = &quot;82801EB/ER (ICH5/ICH5R) AC'97 Audio]

&gt;<i> Can you also attach &quot;amixer -c0&quot; (before running the below commands).
</I>
&gt;<i> More specifically I suspect that the &quot;Master&quot; channel is 0+muted or
</I>&gt;<i> otherwise doing very little.
</I>
# amixer -c0
Simple mixer control 'Master',0
   Capabilities: pvolume pswitch
   Playback channels: Front Left - Front Right
   Limits: Playback 0 - 31
   Mono:
   Front Left: Playback 0 [0%] [-46.50dB] [off]
   Front Right: Playback 0 [0%] [-46.50dB] [off]
...

&gt;<i> A couple things that should get sound are:
</I>&gt;<i>   (as root) alsactl init 0
</I>
With SMplayer already playing a (soundless) DVD iso:
# alsactl init 0
Found hardware: &quot;ICH4&quot; &quot;Analog Devices AD1981B&quot; &quot;AC97a:41445374&quot; &quot;0x1028&quot; 
&quot;0x0151&quot;
Hardware is initialized using a generic method

Still no sound, until turning Kmix up from about 45% default to 100%, which 
gives sound at a level I estimate to be in the vicinity of -40db, barely 
perceptible above the background hum.

&gt;<i> This should &quot;initialise&quot; your card to sensible default which should set
</I>&gt;<i> Master to 55% unmuted.
</I>
55% [-21.00dB][on]

&gt;<i> If that doesn't work, can you try &quot;amixer -c0 set Master 55% unmute&quot;
</I>
&quot;amixer -c0 set Master 85% unmute&quot; helped a lot, but not enough. Hum remains 
unacceptable.

Log out and back in helped more, and bumping to 99%. I still hear the hum, 
but the level seems comparable to that in WinXP.

&gt;<i> Hopefully that'll get sound, but the correct fix is for me to fix this
</I>&gt;<i> in PulseAudio...
</I>
Don't let me get in your way. Thanks! :-)


PS: Could I likely get rid of rest of the hum? Is this normal when as the 
wire crawls 8m or more separates the PC sound jack from the amp?
