| Subject: ALSA: hda: Use LPIB for Acer Aspire 5110 |
| |
| From: Daniel T Chen <crimsun@ubuntu.com> |
| |
| commit 7a68be94e22e7643038726ebc14360752a91800b upstream. |
| |
| BugLink: https://launchpad.net/bugs/583983 |
| |
| Symptom: on a significant number of hardware, booting from a live cd |
| results in capture working correctly, but once the distribution is |
| installed, booting from the install results in capture not working. |
| |
| Test case: boot from Ubuntu 10.04 LTS live cd; capture works correctly. |
| Install to HD and reboot; capture does not work. Reproduced with 2.6.32 |
| mainline build (vanilla kernel.org compile). |
| |
| Resolution: add SSID for Acer Aspire 5110 to the position_fix quirk |
| table, explicitly specifying the LPIB method. |
| |
| I'll be sending additional patches for these SSIDs as bug reports are |
| confirmed. |
