Sound goes too fast due to 798cb7e897210

Dear Takashi,

I have a regression here on 3.1-rc9+ causing the sound "going too fast" with hda. Reverting 798cb7e897210 (ALSA: hda - Fix a regression of the position-buffer check) fixes this regression for me.

Of course, as this commit is itself a regression fix, my goat feeling is that it's not going to be possible to directly revert it. Attached if the output of alsa-info.sh (on the fixed kernel). Please let me know if I can provide you any additional information or test any patch.

Cheers,
Éric

If that commit affects, the best fix would be to give a quirk specific to your device. Try to pass either position_fix=1 or position_fix=2. Only one of them should work (likely 2).

After checking it, you can add it to position_fix_list[] in sound/pci/hda/hda_intel.c together with PCI SSID.

thanks,

Takashi

Hello,
Thanks for the quick response. Indeed forcing position_fix=1 does fix the bug. I'll not try to make a patch for my device.

Cheers,
Éric

At Tue, 18 Oct 2011 10:38:06 +0200,

Hm, interesting. So, in your case, the position-buffer exists and reports some valid values, but the values are sloppy actually. It's hard to detect in the driver, unfortunately. The relevant commit (and its original fix) were the attempts to detect better, but it seems that it fails...

FWIW, the patch below is what I'm committing to the tree.

thanks,

Takashi

Subject: [PATCH] ALSA: hda - Add position_fix quirk for Dell Inspiron 1010

The previous fix for the position-buffer check gives yet another regression on a Dell laptop. The safest fix right now is to add a static quirk for this device (and better to apply it for stable kernels too).

I'm wondering if quirking this based on PCI Vendor-ID would be better than PCI SSID. After all, a broken position buffer should be more of a controller chip problem than a controller/codec/config problem, right?

At Tue, 18 Oct 2011 15:11:23 +0200,

Unfortunately this isn't sure. At least, many Intel chips work fine, so the PCI vendor-id itself isn't correct to use. And PCI SSID vendor alone also is no good way to filter, because it may use different controller chips (like AMD).

The PCI SSID is used now with a hope of that such a breakage won't be too often. And if it's really generic to a PCI controller (vendor/device ID pair), we should put a workaround in driver_caps bits instead.

In general, using LPIB is more reliable. But there are certainly some corner cases that LPIB isn't correct. That was the reason of the previous fix after all.

thanks,

Takashi

Sorry, the PCI VendorID/deviceID was what I meant here. If you need a certain position fix type, isn't it more likely to affect an entire controller, rather than just the controller/codec/config combination that you're quirking?

Again, it's not sure. At least most of the controllers work as is. I bet that the same controller on other machines would work without position_fix quirk.

After all, there are not so many controller chips. If the quirk were mandatory, the list would have been much longer :)
