 Posted: Sat Dec 26, 2015 7:10 pm Post subject: No sound with Broadwell-U Audio Controller |
 |
|
Having issues getting sound on a Dell Lattitude E5550. Trying to follow the Gentoo ALSA wiki.
| Code: |
$ lspci | grep -i audio
00:03.0 Audio device: Intel Corporation Broadwell-U Audio Controller (rev 09)
00:1b.0 Audio device: Intel Corporation Wildcat Point-LP High Definition Audio Controller (rev 03)
|
.config of 4.0.5-gentoo
| Code: |
# HD-Audio
CONFIG_SND_HDA=y
CONFIG_SND_HDA_INTEL=y
CONFIG_SND_HDA_PREALLOC_SIZE=64
CONFIG_SND_HDA_HWDEP=y
CONFIG_SND_HDA_CODEC_HDMI=m
|
Running alsamixer.
| Code: |
$ alsamixer
This sound device doesn not have any controls.
|
My user is in the audio group.
Any thoughts? |

Wizumwalt,
You codec(s) are missing from the kernel?

Well, I added the following based on the only ones I could find that were Intel, but still seeing the same thing.
| Code: | CONFIG_SND_INTEL8X0=y
CONFIG_SND_INTEL8X0M=y
|
Any ideas much appreciated. |

CONFIG_SND_HDA_CODEC_HDMI=m
It's a module, is it loaded?
Edit to add: What does "lspci -nn|grep -i audio" return

Thanks for that, it was not loaded, but still not getting sound. I moved the codec so it is no longer a module and alsamixer now shows S/PDIF, S/PDIF 1, and S/PDIF 2, all unmuted, but seems to show little else.
| Code: |
$ lspci -nn | grep -i audio
00:03.0 Audio device [0403]: Intel Corporation Broadwell-U Audio Controller [8086:160c] (rev 09)
00:1b.0 Audio device [0403]: Intel Corporation Wildcat Point-LP High Definition Audio Controller [8086:9ca0] (rev 03)
|
Also ...
| Code: |
$ speaker-test -t wav -c 2
speaker-test 1.0.29
Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
WAV file(s)

| I guess you need the module "snd_hda_codec_realtek". Do you have that kernel option enabled? |

Not sure why I would need realtek, but I added it and still have the same issues. |

If you have systemrescuecd you could fire it up, see if sound works and if so, do an lsmod to see what modules are loaded.
Note: systemrescuecd is always a good program to keep around.

Sorry I didn't explain it. I searched for your laptop and found that it comes with RealTek ALC3234/ALC3235, which is supposed to be handled by the "snd_hda_code_realtek" module. |

For reasons unknown to me the driver selects the first hdmi device as default card. You could try this config in your ~/.asoundrc to fix that and see whether you have sound afterwards ...
| Code: | # Switch default card from hdmi to analog
# - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
pcm.!default {
type hw
card 1
}
ctl.!default {
type hw
card 1
}

No, it started consuming too much time to figure out. But jumping back into the problem once again.  |

More generic solution would be to place
| Code: | defaults.pcm.card 1
defaults.ctl.card 1
|
into
where number is picked according to | Code: | | cat /proc/asound/cards |
as stated in https://www.alsa-project.org/main/index.php/Setting_the_default_device
(wouldn't figure it out without swimmer, so big thanks to him/you!) |

I have the same "Audio device: Intel Corporation Broadwell-U Audio Controller (rev 09)" [here (rev 08) though] in a Dell laptop. Just spent some time to figure out the the correct kernel settings (on ver >5.1). Thanks goes to gentoo irc for showing in the right direction (iamben) and helping to solve the issue.
After booting into a live system and checking dmesg and lsmod I noticed that audio required rt286 drivers. If you use "make menuconfig" for kernel configuration and search for rt286, relevant settings will be shown - these also depend on the CPU type, so make sure to choose the settings according to your machine. For me relevant settings were:
| Code: | Device Drivers
[M] Sound card support
[M] Advanced Linux Sound Architecture
[M] ALSA for SoC audio support
[*] Intel ASoC SST drivers
[M] Haswell/Broadwell Platforms
and here also:
[M] All Skylake/SST Platforms
[*] HDAudio codec Support
[*] Intel Machine drivers
[M] Broadwell Wildcatpoint
[M] SKL/KBL/BXT/APL with HDA Codecs |
| Code: | Device Drivers
[*] I2C support
I2C Hardware Bus support
[*] Synopsys DesignWare Platform |
| Code: | Device Drivers
Multifunctional device drivers
[*] Intel Low Power Subsystem support in ACPI mode |
With these settings audio works, for HDMI audio support:
| Code: | Device Drivers
[M] Sound card support
[M] Advanced Linux Sound Architecture
HD-Audio
[M] HD Audio PCI
[M] Build Realtek HD-audio codec support
[M] Build HDMI/Displayport HD-audio codec support
[M] Enable generic HD-audio codec parser |
I'm not sure about microphone support yet (Generic Digital Microphone CODEC) and if setting AC97 (Build generic ASoC AC97 CODEC driver) would have any advantages (atm audio works fine without it). For me it was NOT necessary to change any of the alsa config files. Just for the record: user is member of the audio group. |

wozencroft,
AC97 is an alsa sound driver made popular about 20 years ago.
It would be unusual to find HDA and AC97 devices in the same system so I would expect that the AC97 options do nothing for you.

@NeddySeagoon
Yep, that's also what I was thinking of. However while tweaking those settings I noticed (lsmod) the module "ac97_bus" loaded (after that ac97 setting was enabled), which is used by "snd_soc_core" according to the output. This is why I was wondering about if it's maybe relevant for some corner cases (flags?), but probably not. Audio works fine in both cases. |
