 Posted: Fri Jun 24, 2016 7:04 am Post subject: New install, no sound![SOLVED] |
 |
|
Hi everyone
I am new to Gentoo, so please forgive any stupid questions 
I have just Installed Gentoo with the following profile
| Code: |
[6] default/linux/amd64/13.0/desktop/kde *
|
But I am not getting any sound while playing video in VLC or streaming Youtube in Firefox/Chromium. I am not getting any system sound either!
I had the following lines in my /etc/portage/make.conf during install
| Code: |
CFLAGS="-O2 -march=amdfam10 -pipe"
CXXFLAGS="${CFLAGS}"
MAKEOPTS="-j2"
USE="-gtk -gnome icu qt4 kde dvd pulseaudio alsa bindist mmx sse"
INPUT_DEVICE="evdev"
VIDEO_CARDS="radeon"
|
I have the following hardware.
Processor Athlon XII 250
M/B MSI 880GMA-E35(FX). This is a board with AMD 880 chipset with Radeon HD 4250 IGP.
The IGP supports native HD video decode features, as well as HDMI with on-chip 7.1 channel audio (I only have 2.1 speakers though).
I am using an external Radeon HD 6570 PCIe card and have disabled the IGP in BIOS.
Integreated Audiois on though.
My non-root user is in the following groups
10(wheel),18(audio),27(video),100(users),998(vboxusers)
I have also made changes to my kernel as suggested by these pages
https://wiki.gentoo.org/wiki/ALSA#Kernel
| Code: |
Device Drivers --->
<*> Sound card support
<*> Advanced Linux Sound Architecture --->
[*] PCI sound devices --->
Select the driver for your audio controller, e.g.:
<*> Intel HD Audio ---> (snd-hda-intel)
Select a codec or enable all and let the generic parse choose the right one:
[*] Build Realtek HD-audio codec support
[*] ...
[*] Build Silicon Labs 3054 HD-modem codec support
[*] Enable generic HD-audio codec parser
General setup --->
[*] System V IPC
|
https://wiki.gentoo.org/wiki/PulseAudio#Kernel
| Code: |
Device Drivers --->
<*> Sound card support --->
<*> Advanced Linux Sound Architecture --->
HD-Audio --->
(2048) Pre-allocated buffer size for HD-audio driver
|
I can’t be sure if I did everything correctly, it would really help if someone could check and confirm.

There is an alarming bit in dmesg, though I don’t know what to make of it!?
I am no expert and I am just trying to follow instructions to get things to work.
| Code: |
[ 3.873760] hdaudio hdaudioC1D0: Unable to bind the codec

lspci -k shows the following audio devices
| Code: |
01:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Turks/Whistler HDMI Audio [Radeon HD 6000 Series]
Subsystem: PC Partner Limited / Sapphire Technology Turks/Whistler HDMI Audio [Radeon HD 6000 Series]
Kernel driver in use: snd_hda_intel
00:14.2 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] SBx00 Azalia (Intel HDA) (rev 40)
Subsystem: Micro-Star International Co., Ltd. [MSI] SBx00 Azalia (Intel HDA)

Starting alsamixer I can see the following under [Playback]
| Code: |
Card: PulseAudio
Chip: PulseAudio
|
there is only one channel!! <Master> and it’s NOT muted, volume is at 100%
Pressing F5 to see all,
I get another channel!! <Capture> it’s probably the mic of my Logitech C310 USB webcam.
Pressing ‘F2’ to see systeminfo from /proc/asound/cards
| Code: |
0 [SB ]: HDA-Intel - HDA ATI SB
HDA ATI SB at 0xfe7f8000 irq 16
1 [HDMI ]: HDA-Intel - HDA ATI HDMI
HDA ATI HDMI at 0xfe8f8000 irq 30
2 [U0x46d0x81b ]: USB-Audio - USB Device 0x46d:0x81b
USB Device 0x46d:0x81b at usb-0000:00:16.2-2, high speed
|
Pressing ‘F6’ to Select sound card I get the following
| Code: |
- (default)
0 HDA ATI SB
1 HDA ATI HDMI
2 USB Device 0x46d:0x81b
|
Selecting card 0 gives
| Code: |
Card: HDA ATI SB
This sound device does not have any controls.
|
Selecting card 1 gives
| Code: |
Card: HDA ATI HDMI
This sound device does not have any controls.
|
Selecting card 2 gives
| Code: |
Card: USB Device 0x46d:0x81b
Chip: USB Mixer
Item: Mic [dB gain: 25.50]
|
and a volume control bar for the channel <Mic>; volume is at 90%.
In KDE -> System Settings -> Multimedia -> Audio & Video Setting ->Settings for the Phonon multimedia framework….
Under the Device Preference tab
>|Audio playback
>|Music
there is only ‘Dummy Output’ on the right hand panel!!
Under the Device Preference tab
>|Audio Hardware Setup
>|Sound Card
there is only ‘Webcam C310’ and ‘Independent Device’. I guess the mic seems to be working nicely as the ‘Input Level’ bar indicator keeps fluctuating, and spikes to maximum when I speak into the Webcam.
If I select ‘Independent Device’ as the sound card then there is only ‘Playback (Dummy output device)’ under ‘Sound Device’.
Under the Backend tab
there is only VLC.
So where have I gon wrong??

I may have narrowed down the problem a bit..
First I booted with the Install media to check if everything works, and sure enough it did.
So I am comparing the boot disk setting with my install settings.....
speaker-test -t wav -c 2
Worked flawlessly on the boot disk!
On my local install it did not produce any errors, but did not produce any sound either!!
| Code: | speaker-test 1.0.29
Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
WAV file(s)
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 96 to 1048576
Period size range from 32 to 349526
Using max buffer size 1048576
Periods = 4
was set period_size = 262144
was set buffer_size = 1048576
0 - Front Left
1 - Front Right
Time per period = 4.698917
0 - Front Left
1 - Front Right
Time per period = 4.508813
0 - Front Left
^C 1 - Front Right

This is where things start to get interesting.. notice the difference carefully, both in the codes and the loaded modules
cat /proc/asound/card0/codec#0 | head

It produced NOTHING!!!!!!????
What gives man....?? how come...??
Is it because I had ALSA built-in into the kernel and lsmod only shows loaded modules?? but the drivers/codecs under ALSA was compiled as modules...!
Anyways, I am hoping someone else can make better sense of all these.
Thanks

Do you use genkernel?
If not did you install the modules? |

Yes, I use Genkernel....
I hope someday future generation will find this info handy
On a hunch (almost out of nowhere) I recompiled the kernel, only this time I compiled ALSA as a module and everything works fine now 
Link to this kernel config below, if anybody is interested to check the diff.
