Here are some patches for ALSA to fix issues with 5.1 surround in some machines (LG LW20 laptop, HP Nettle, HP Lucknow), headphone detection (HP Spartan laptop), modem detection (Clevo m540 laptop, sold under different names such as Positivo V44 in Brazil) and USB MIDI quirk (Roland Juno-G synth). All those were sent to Takashi for inclusion in 2.6.23, but if you’re stuck with an older kernel, can’t upgrade your ALSA and have experienced problems with any of the pieces of hardware listed above, you can try one or more of the following patches:
- Fix 5.1 output in LG LW20
- Add quirk for Roland Juno-G (use if usb-midi doesn’t work)
- Add quirk for HP Spartan (fixes headphone detection)
- Add quirk for HP Nettle
- Fix 5.1 surround in HP Nettle
- Add HP Lucknow 5.1 sound support
- Add quirk for si3054 modem detection in Clevo m540
