#178678 — Sound Problem

From"Stephen P. Molnar" <s.molnar@sbcglobal.net>

SubjectSound Problem
Message-ID<tjQlz-44i-3@gated-at.bofh.it>
Up to date Jessie.

Sound worked until I turned power off to the external speakers.  The 
sound has not been working since I turned the speakers back on.

If I run 'speaker-test' I get noise, but if I run 'speaker-test -c 2 -t
wav' I get 'front left' and 'front right' from the speakers.

I am using the on-board sound:

01:00.1 Audio device: NVIDIA Corporation GF119 HDMI Audio Controller 
(rev a1)
	Subsystem: Micro-Star International Co., Ltd. [MSI] Device 809f
	Flags: bus master, fast devsel, latency 0, IRQ 25
	Memory at fe080000 (32-bit, non-prefetchable) [size=16K]
	Capabilities: [60] Power Management version 3
	Capabilities: [68] MSI: Enable- Count=1/1 Maskable- 64bit+
	Capabilities: [78] Express Endpoint, MSI 00
	Kernel driver in use: snd_hda_intel

I have proven, to my satisfaction, thanks to a suggestion from a 
correspondent, that this is not a hardware problem.  I loaded the 
Xubuntu 17.04 Live Desktop on the computer and the sound is live.

I would appreciate some help in solving this problem.

Thanks in advance.

In my experience, problems like this are nearly always problems
in software selection of output and/or mixer volumes.

The card that you are selecting there is an HDMI audio
controller, which means that it is a sound card which only
outputs through the HDMI connection going to a TV or video
monitor. Is that what you are expecting?

If, as is more usual, you are expecting to output through 1/8"
stereo jacks to self-powered speakers or 1/8" line-level stereo
to an amplifier, you need to select that sound card and use it.

aplay -L should give you a list of possible outputs, one of
which  you can then feed to speaker-test via -D to test.

Then you can set this in /etc/asound.conf as a default. Mine
says

defaults.pcm.card 0
defaults.pcm.device 3
defaults.ctl.card 0

Thanks for the reply.  I had pretty well convinced myself that it's a 
software problem,  and therein lies the rub (or, rather a very high 
degree of entropy (mixedupness)).

Here is what might be the applicable portion on the output from aplay -L:

sysdefault:CARD=SB
     HDA ATI SB, ALC887-VD Analog
     Default Audio Device
front:CARD=SB,DEV=0
     HDA ATI SB, ALC887-VD Analog
     Front speakers
surround21:CARD=SB,DEV=0
     HDA ATI SB, ALC887-VD Analog
     2.1 Surround output to Front and Subwoofer speakers
surround40:CARD=SB,DEV=0
     HDA ATI SB, ALC887-VD Analog
     4.0 Surround output to Front and Rear speakers
surround41:CARD=SB,DEV=0
     HDA ATI SB, ALC887-VD Analog
     4.1 Surround output to Front, Rear and Subwoofer speakers
surround50:CARD=SB,DEV=0
     HDA ATI SB, ALC887-VD Analog
     5.0 Surround output to Front, Center and Rear speakers
surround51:CARD=SB,DEV=0
     HDA ATI SB, ALC887-VD Analog
     5.1 Surround output to Front, Center, Rear and Subwoofer speakers
surround71:CARD=SB,DEV=0
     HDA ATI SB, ALC887-VD Analog
     7.1 Surround output to Front, Center, Side, Rear and Woofer speakers

and, this is what I get from aadebug:

0 [SB             ]: HDA-Intel - HDA ATI SB

                       HDA ATI SB at 0xfe300000 irq 16

also, that is what alsamixer is giving as the default.

So my degree of mental entropy is high and increasing (a thermodynamic 
requirement for an allowed process).

Your further comments will be much appreciated.

Thanks in advance.

I would try 

speaker-test -D front 

and see if that comes out the right device.

Thanks for the reply.. That resulted in the 'front right' 'front left'

As you most likely have two sound cards, one on-board and one with the
video card (HDMI) it may be worthwhile installing pasystray as this may
give you better control over which card you want to use, lots of
options to reset sink, add modules etc. It helped me solve sound issues
in the past when switching between on-board headphones and HDMI to the
TV so worth a try at least.

Thanks for the suggestion.

Here's what happens:

comp@AbNormal:~$ /usr/bin/pasystray
** Message: volume:53085

Then nothing.

To get my sound working after a reboot I have to 'sudo alsactl init'.
And then I load alsamixer, choose my soundcard and turn all bars up to
100%.

Maybe this would help solve your problem?
