 Posted: Fri Feb 20, 2009 10:32 pm Post subject: Sound on hda_intel device not good (Lenovo Y530) [SOLVED] |
 |
|
Have a Lenovo Y530 with a sound card compatible with snd_hda_intel module.
I compiled the hda intel module on kernel 2.6.27 (and added all codecs, not sure if i needed, because if i use the generic one, it works)
I have stable alsa 1.0.17 , and also tried unstable 1.0.19
Dmesg reports:
| Code: |
HDA Intel 0000:00:1b.0: PCI INT A disabled
HDA Intel 0000:00:1b.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22
HDA Intel 0000:00:1b.0: setting latency timer to 64
hda_codec: Unknown model for ALC883, trying auto-probe from BIOS...
|
in alsamixer, appears:
| Code: |
Card: HDA Intel │
Chip: Realtek ALC888
|
This laptop is a 4.1, and only side columns sound (2 in front and one under, does not work).
The sound is low (far from maximum, maximum sound is normal), and micro has low sound capture also
Quality of sound is also inferior comparing with the standard wind. instalation that the laptop has.
I added this
| Code: |
options snd_hda_intel model=lenovo-sky
|
to /etc/modules.autoload.d/kernel-2.6 and now it forces the kernel to loadit instead of udev (but i doubt the option is usefull, i do not see it on my linux source). And i can't see the parameter in /sys/module/....
See some details of laptop here: http://www.linlap.com/wiki/Lenovo+IdeaPad+Y530. My laptop has some different specs, but i think that sound card is the same.

I'd recommend ALSA 1.0.19 as I haven't had much luck since 1.0.15 (and even that was dodgy.) So far 1.0.19 has been perfect. I'd also try a newer kernel, they're adding support for these devices all the time, and 2.6.27 is quite old now (I upgraded from 2.6.28-rc2 to 2.6.28.3 and in that jump they'd added support for my ALC889.)
Otherwise what you've done with the module parameter is fine, all you need to do is verify that the kernel is actually picking up that parameter (just in case) and then try all the different options listed in the ALSA docs. You should find at least one of them works properly! |

I tried ALSA 1.0.19 and Zen Gentoo Kernel 2.6.29 and nothing. It seems the same behaviour. The codec was different (NVIDIA ID 3). But the same controls.
Back to stable. Wireless did not work.
Any form of feedback to ALSA? |

I found a good solution at https://forums.gentoo.org/viewtopic-t-728396-highlight-.html
Lenovo ideapad Y510 is similar to ideapad Y530
Starting kernel 2.6.28 pass model "lenovo-sky" to snd_hda_intel module (i use realtek codec, and generic codec on compilation). It works without any headphone problem. |
