http://bugzilla.suse.com/show_bug.cgi?id=1089467 Bug ID: 1089467 Summary: dell 5520 docking station WD15 poor audio quality Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: bpoirier@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- When first playing a sound, there is some delay (noticeable but less than 1s), then a click, then the sound, then 10s later another click. It seems like some circuit of the audio card is activated and deactivated. It is quite annoying since AFAIK the laptop has no bell so I use this sound card to handle x11 bell events. In this case, the delay and the clicks/pops are easily noticeable. This does not happen when playing sound through the built-in audio card. -- You are receiving this mail because: You are on the CC list for the bug.

(BTW, it's not about audio "quality" but audio "latency".) I have a plan to improve the latency (that was also requested from Google people for Android), but had no time for it, so far. That said, it's not a thing to be fixed quickly, but needs a fundamental rework. So need to resolve as FEATURE for now, sorry. Let's hope that the next hack week helps in this regard :) -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.suse.com/show_bug.cgi?id=1089467 http://bugzilla.suse.com/show_bug.cgi?id=1089467#c2 --- Comment #2 from Takashi Iwai --- Now I got a Dell dock from Oliver, and tested by myself. And I conclude that this is really a hardware problem. When we change the USB interface via usb_set_interface(), this already introduce a long delay. The other places are processed quickly enough. In the rest stream, there is no significant click on the dock I tested, so it's also likely a firmware problem. So it's not about the latency I firstly suspected with the USB-audio driver design, but it's a XXXX of hardware, after all (place any four letters there). You may try to upgrade the Dock BIOS. At least Realtek engineers recommended it in the past. But it needs to be done via Windows :-< -- You are receiving this mail because: You are on the CC list for the bug.

Since the problem is about the usb_set_interface(), if we may reduce this calls, it should work better for this device. And the result looks positive. The patch below is a test patch for the upstream tree. Could you give it a try? -- You are receiving this mail because: You are on the CC list for the bug.

There is no more sound output! pavucontrol shows the meter which makes it look like there should be sound. With the same patch I did have sound out the laptop speakers. I reverted just that patch and sound was working again through the dock (with the same delays and click/pops). -- You are receiving this mail because: You are on the CC list for the bug.

OK, then at this point, please try with snd_usb_audio.keep_iface=1 option. This should break the sound again. I'd like to be sure that the problem is persistent.

With the changes in sound/usb/quirks-table.h restored (ie. the content of the patch from comment 4) and snd_usb_audio.keep_iface=1, no audio. (In reply to Takashi Iwai from comment #9)

One another thing to try the patch below. Apply it after the previous patch. It may fix the missing sound or the bad quality.

With the second patch, same result - no audio. -- You are receiving this mail because: You are on the CC list for the bug.

The point is to check whether setting keep_iface field makes the things broken or not, or it's something else. But maybe it's just the device being so broken. Also, try the second patch alone without the first one. I'd like to know whether the second patch has any influence on the audio quality (crackling noise or such). I'm afraid that your device has the too old BIOS. The dock stores its own BIOS, and the old BIOS is known to be pretty buggy. In that sense, this bug report will be likely WONTFIX / INVALID. But at least let's see whether we can get any possible workaround. -- You are receiving this mail because: You are on the CC list for the bug.

It's a BIOS setup, and the behavior seems different depending on the power state. For example, I could hear some noise only after a cold boot. It could be addressed by the second patch. -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.suse.com/show_bug.cgi?id=1089467 http://bugzilla.suse.com/show_bug.cgi?id=1089467#c14 --- Comment #14 from Benjamin Poirier --- I repeated the tests. For each test I observed the result i) after reboot, ii) after poweroff + boot, iii) after poweroff + unplug + boot. For both tests the results from those three variants were identical: 1) patch from comment 4, revert the changes in quirks-table.h, snd_usb_audio.keep_iface=1 no audio 2) patch from comment 10 by itself delay and click/pop like in comment 0 The next two days are holidays. Next week I will try to update the WD15 firmware. -- You are receiving this mail because: You are on the CC list for the bug.

At least it's good to know that the second patch doesn't break things. This one can be upstreamed. I plan to implement the first one with the dynamic switch via ALSA control element; as default turned off, but changed on the fly if someone wants to play. It can be a workaround for the known working devices, at least. -- You are receiving this mail because: You are on the CC list for the bug.

I'm afraid that your device has the too old BIOS. The dock stores its own BIOS, and the old BIOS is known to be pretty buggy. In that sense, this bug report will be likely WONTFIX / INVALID. But at least let's see whether we can get any possible workaround.

Today I tried updating the dock firmware using DellDockingStationFwUp_1.0.0.8_20161220_WD15.exe After a few seconds (without a reboot) it said that the firmware was up to date. (IMO, either it was already up to date or the update failed...) I also updated the laptop firmware using Precision_5520_1.9.4.exe In the end there was no improvement to the audio quality. The symptoms remain as described in c0. -- You are receiving this mail because: You are on the CC list for the bug.

But it's not a thing we can "fix" in the distro side, by obvious reason. So this bug is still WONTFIX or FEATURE. -- You are receiving this mail because: You are on the CC list for the bug.
