Hi, I'm running stock Debian Wheezy (7.1) --- except for a kernel upgrade (3.10-0.bpo.2-amd64) from Debian backports --- as well as XFCE, on a couple different hardware configs. However, I'm struggling to get audio to work properly on my new Intel Haswell board. (1) On a Thinkpad x220: Audio works great, out of the box (2) On a Supermicro X10SLQ (Q87 chipset) with Haswell i4770S: Audio doesn't work at all --- no audio at all comes out of standard rear headphone jack. (NOTE: Supermicro website identifies audio capabilities as provided by onboard RealTek ALC888S chipset, but lspci [below] instead identifies Intel HDA audio, courtesy of Haswell. I worry that this might be an issue.) Could this be an issue with the kernel, or should I be looking elsewhere. I was under the belief that 3.10 (unlike the 3.2 kernel that shipped with Wheezy) had fairly comprehensive support for Haswell in general! Some more information is attached below... I don't have much experience trouble-shooting audio problems, so I appreciate any suggestions / pointers. Thanks! ---------------------------------------------------------------------- guest@haswell:~$ lspci -v | grep -i -A8 audio 00:03.0 Audio device: Intel Corporation Haswell HD Audio Controller (rev 06) Subsystem: Intel Corporation Device 2010 Flags: bus master, fast devsel, latency 0, IRQ 52 Memory at f0534000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit- Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00 Kernel driver in use: snd_hda_intel -- 00:1b.0 Audio device: Intel Corporation Lynx Point High Definition Audio Controller (rev 04) Subsystem: Super Micro Computer Inc Device 0654 Flags: bus master, fast devsel, latency 0, IRQ 53 Memory at f0530000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+ Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00 Capabilities: [100] Virtual Channel Kernel driver in use: snd_hda_intel guest@haswell:~$ lsmod | grep snd snd_hda_codec_realtek 32712 1 snd_hda_codec_hdmi 31720 1 snd_hda_intel 35718 5 snd_hda_codec 122850 3 snd_hda_codec_realtek,snd_hda_codec_hdmi,snd_hda_intel snd_hwdep 13189 1 snd_hda_codec snd_pcm 68525 3 snd_hda_codec_hdmi,snd_hda_codec,snd_hda_intel snd_page_alloc 13018 2 snd_pcm,snd_hda_intel snd_seq 45186 0 snd_seq_device 13176 1 snd_seq snd_timer 22773 2 snd_pcm,snd_seq snd 53068 19 snd_hda_codec_realtek,snd_hwdep,snd_timer,snd_hda_codec_hdmi,snd_pcm,snd_seq,snd_hda_codec,snd_hda_intel,snd_seq_device soundcore 13026 1 snd guest@haswell:~$ dmesg | grep -i sound [ 2.007991] input: HDA Intel MID HDMI/DP,pcm=8 as /devices/pci0000:00/0000:00:03.0/sound/card0/input6 [ 2.008079] input: HDA Intel MID HDMI/DP,pcm=7 as /devices/pci0000:00/0000:00:03.0/sound/card0/input7 [ 2.008131] input: HDA Intel MID HDMI/DP,pcm=3 as /devices/pci0000:00/0000:00:03.0/sound/card0/input8 [ 2.034368] input: HDA Intel PCH Front Headphone as /devices/pci0000:00/0000:00:1b.0/sound/card1/input9 [ 2.034620] input: HDA Intel PCH Line Out CLFE as /devices/pci0000:00/0000:00:1b.0/sound/card1/input10 [ 2.034834] input: HDA Intel PCH Line Out Surround as /devices/pci0000:00/0000:00:1b.0/sound/card1/input11 [ 2.035018] input: HDA Intel PCH Line Out Front as /devices/pci0000:00/0000:00:1b.0/sound/card1/input12 [ 2.035199] input: HDA Intel PCH Line as /devices/pci0000:00/0000:00:1b.0/sound/card1/input13 [ 2.035383] input: HDA Intel PCH Rear Mic as /devices/pci0000:00/0000:00:1b.0/sound/card1/input14 [ 2.035565] input: HDA Intel PCH Front Mic as /devices/pci0000:00/0000:00:1b.0/sound/card1/input15 guest@haswell:~$ _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
