Pop sound on each playback start and stop Audigy 2 ZS

bbarcher · 2014-05-23 20:35:52

I've been getting it on every distro I've tried and on all kernels (I bought the card circa kernel 2.8 times I think). I've had enough. The popping is so annoying. When I use volume keys of my laptop on Gnome which has the 'tok' even sound for each stroke I hear *two* pops for each 'tok'! It can even be heard during dialogs on some YT videos.

I don't care about powersaving. I just want the popping to finally go away. I'd appreciate any help.

What I've tried:
1. disabling power saving
a) using TLP: SOUND_POWER_SAVE=0 SOUND_POWER_SAVE_CONTROLLER=N
b) /etc/pulse/default.pa : #load-module module-suspend-on-idle
c) modprobe snd_emu10k1 power_save=0
d) /etc/pulse/default.pa load-module module-udev-detect tsched=0
e) disabling all powersaving options in BIOS

2. enabling Line in alsamixer (no 'automute' option there BTW)

I assume you ruled pulseaudio out. Please provide the vid and pid:

lspci -nn | grep -i audio;

What about module option "high_res_gpr_volume"? Did you check out emu-tools? (qlo10k1) This sounds like each command send resets volume level briefly before updating them.
Are you positive this does not come from the intel card? I assume it is integrated, so you probably could disable it for one boot, just to make sure.

bbarcher · 2014-05-24 09:29:16

Same as # lspci | grep -i audio

# lspci -nn | grep -i audio;
00:1b.0 Audio device [0403]: Intel Corporation 82801I (ICH9 Family) HD Audio Controller [8086:293e] (rev 03)
16:00.0 Multimedia audio controller [0401]: Creative Labs SB0400 Audigy2 Value [1102:0008]

high_res_gpr_volume:
What about it? I assume it's an 'option'. How do I disable it to stay disabled even after reboots? Looking at the list of the parms I'd try disabling "delay_pcm_irq" as well.

emu-tools:
I haven't tried them. In what way do they suppose to help me? The docs don't mention power saving options.

Can the intel audio cause this?
I'm sure it can't. The 'pop!' is pretty much the same as during boot when the Audigy gets powered up. Besides, I've disabled audio powersaving in TLP *which applies only to Intel audio*. Confirmed using powertop - Intel audio (conexant) is at 100% 'usage'.

I forgot to add. This is a PCMCI card in Thinkpad T500.

I do not have a sound card with the emu10k1 ic, so emu-tools might be unrelated, but might also have settings for your case.

The point of lspci -nn is to get vid and pid, like I already stated. You missed the difference? But yes, it is in the code, no problems here. Also searching for vid:pid combo, might narrow down the issue faster.

The high_res_gpr_volume is listed as an option in the output you provided. You first enable it by editing a conf file in /etc/modprobe.d:

options snd-emu10k1 high_res_gpr_volume=1

To disable it drop the option or delete the whole file.

Did you rule out pulseaudio or not?

My /etc/modprobe.d dir is empty. Do you mean e.g. /etc/modprobe.d/modprobe.conf?

emeres · 2014-05-24 12:14:46

man modprobe.d

Just create a file with conf extension and put the options in there. You can name it 60-emu10k1.conf.

bbarcher · 2014-05-24 12:21:25

I know but I'd prefer to keep all the options I'm going to use in one file. I'll comment it appropriately. I'll try

options snd_emu10k1 power_save=0 power_save_controller=N options snd-emu10k1 high_res_gpr_volume=0

I didn't know the values are of any importance

What value would you recommend for the "delay_pcm_irq"?

BTW, I've edited post #1. Added item 1.d) as well as post #3 to add 'Can the intel audio cause this?' info.
Could you edit you rpost #4? snd-emu10k1 -> snd_emu10k1

emeres · 2014-05-24 12:27:19

Try

options snd_emu10k1 power_save=0 power_save_controller=0 high_res_gpr_volume=0 delay_pcm_irq=0

And then every other combination, you may want to skip the power saving options. You should also be able to unload the module and load it with options on the fly without the need for reboot, although that would be the way to go, since sometimes hardware needs to power down before accepting new parameters.

bbarcher · 2014-05-24 12:47:18

The line didn't help. I did reboot. This pretty much axhausts the possibilities. Against what package I should file the bug report? Kernel?

emeres · 2014-05-24 13:16:35

I see 4 possibilities:

high_res_gpr_volume == a; delay_pcm_irq == b;
 a | b 
-------
 0 | 0
 0 | 1
 1 | 0
 1 | 1

Ad Kernel: That is probably the best bet. You could try asking alsa devs on alsa-user mailing list also.

delay_pcm_irq is 'array of int'. Are you sure it's only 0 or 1?

emeres · 2014-05-24 13:42:25

Right, an array of unsigned integers to be exact. You would have to look at the code, either in your sources or here and here. They may have changed somewhat, but I doubt any drastic changes. First link is to linux 3.14 version. At least I assume it gets passed on directly, if that really is the case, I do not know. Just try it, hardware damage risk is minimal.

Looking at the mask, I think it takes up to 31 samples. So try with 1, 2, 4, 8, 16, 24. I may be very well wrong about this.

Why? Modprobe should not care about hyphen or underscore. They should be always converted when parsing. On most keyboard layouts (also on the Polish programmer one) hyphen is one key one keystroke, where underscore is two key one keystroke, therefore more error prone and less efficient.

Since I already have 0 and 1 in the 'trial matrix' I'll add 24 only. Adding the combinations with 2, 4, 8, 16, 24 is too much for me

Wow, I didn't know that! What do you know! Linux being bitchy even about capital letters made me think it would be even more bitchy about '_' vs '-'.

Both are interpreted as different characters, as any other characters are. It just happens that modprobe does not care. Windows does not respect capital and small letters distinction on the filesystem, if I recall correctly.

If it does not work, again, either ask on alsa mailing list or file a bug report, like you suggested. Please link any outside activity that may benefit other people here.

I've just got rid of the pops. The last thing I did was killing the Intel HD Audio altogether by blacklisting the following modules in /etc/modprobe.d/modprobe.conf
:
[codec]
blacklist snd_hda_codec_conexant
blacklist snd_hda_codec_generic
blacklist snd_hda_intel
blacklist snd_hda_codec
[/codec]
I did it to basically get rid of the built-in (i.e. Intel HD Audio one) microphone that was constantly working in the background. I'll report back on what happens after I re-enable the Intel audio.
