On ThinkPad T520 (Intel Sandybridge) with 4.14-rc4 + two BTRFS patches and one Intel P-State debug patch I have no sound output on internal Intel HD audio codec. According to ThinkPad T520 LED with striked-through speaker the loud speaker is in disabled state. Also KDE?s Phonon says a soundcard is missing. In alsa-mixer I see nothing as MM for muted. If I press the key next to the LED I get a notification on the desktop that loud speaker has been enabled / disabled, but the LED still is on for it being disabled. I do not hear anything in Amarok or with aplay. alsa-mixer sound volumes are 100 for master and PCM. I also tried with disabling "Auto-Mute Mod", but still no sound. When I reboot and in BIOS or GRUB press the key then the LED toggles state. When I reboot into Linux 4.0.1 sound is working fine and loud speaker disabled LED is toggled off, so I bet this is a regression 4.1-rc4 compared to 4.0.1. The following is from non-working 4.1-rc4 kernel: merkaba:~> lspci -s 00:1b.0 -nnv 00:1b.0 Audio device [0403]: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller [8086:1c20] (rev 04) Subsystem: Lenovo Device [17aa:21cf] Flags: bus master, fast devsel, latency 0, IRQ 29 Memory at f2520000 (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 Capabilities: [130] Root Complex Link Kernel driver in use: snd_hda_intel merkaba:~> cat /proc/asound/cards 0 [PCH ]: HDA-Intel - HDA Intel PCH HDA Intel PCH at 0xf2520000 irq 29 merkaba:~> cat /proc/asound/version Advanced Linux Sound Architecture Driver Version k4.1.0-rc4-tp520-btrfstrim- pstatetrace+. merkaba:~> cat /proc/asound/devices 2: [ 0] : control 3: [ 0- 0]: digital audio playback 4: [ 0- 0]: digital audio capture 5: [ 0- 3]: digital audio playback 6: [ 0- 7]: digital audio playback 7: [ 0- 8]: digital audio playback 8: [ 0- 0]: hardware dependent 9: [ 0- 1]: hardware dependent 10: [ 0- 3]: hardware dependent 33: : timer merkaba:~> merkaba:~> aplay -L null Discard all samples (playback) or generate zero samples (capture) pulse PulseAudio Sound Server phonon HDA Intel PCH mit Mixer default:CARD=PCH HDA Intel PCH, CX20590 Analog Default Audio Device sysdefault:CARD=PCH HDA Intel PCH, CX20590 Analog Default Audio Device front:CARD=PCH,DEV=0 HDA Intel PCH, CX20590 Analog Front speakers surround21:CARD=PCH,DEV=0 HDA Intel PCH, CX20590 Analog 2.1 Surround output to Front and Subwoofer speakers surround40:CARD=PCH,DEV=0 HDA Intel PCH, CX20590 Analog 4.0 Surround output to Front and Rear speakers surround41:CARD=PCH,DEV=0 HDA Intel PCH, CX20590 Analog 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=PCH,DEV=0 HDA Intel PCH, CX20590 Analog 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=PCH,DEV=0 HDA Intel PCH, CX20590 Analog 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=PCH,DEV=0 HDA Intel PCH, CX20590 Analog 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers hdmi:CARD=PCH,DEV=0 HDA Intel PCH, HDMI 0 HDMI Audio Output hdmi:CARD=PCH,DEV=1 HDA Intel PCH, HDMI 1 HDMI Audio Output hdmi:CARD=PCH,DEV=2 HDA Intel PCH, HDMI 2 HDMI Audio Output dmix:CARD=PCH,DEV=0 HDA Intel PCH, CX20590 Analog Direct sample mixing device dmix:CARD=PCH,DEV=3 HDA Intel PCH, HDMI 0 Direct sample mixing device dmix:CARD=PCH,DEV=7 HDA Intel PCH, HDMI 1 Direct sample mixing device dmix:CARD=PCH,DEV=8 HDA Intel PCH, HDMI 2 Direct sample mixing device dsnoop:CARD=PCH,DEV=0 HDA Intel PCH, CX20590 Analog Direct sample snooping device dsnoop:CARD=PCH,DEV=3 HDA Intel PCH, HDMI 0 Direct sample snooping device dsnoop:CARD=PCH,DEV=7 HDA Intel PCH, HDMI 1 Direct sample snooping device dsnoop:CARD=PCH,DEV=8 HDA Intel PCH, HDMI 2 Direct sample snooping device hw:CARD=PCH,DEV=0 HDA Intel PCH, CX20590 Analog Direct hardware device without any conversions hw:CARD=PCH,DEV=3 HDA Intel PCH, HDMI 0 Direct hardware device without any conversions hw:CARD=PCH,DEV=7 HDA Intel PCH, HDMI 1 Direct hardware device without any conversions hw:CARD=PCH,DEV=8 HDA Intel PCH, HDMI 2 Direct hardware device without any conversions plughw:CARD=PCH,DEV=0 HDA Intel PCH, CX20590 Analog Hardware device with all software conversions plughw:CARD=PCH,DEV=3 HDA Intel PCH, HDMI 0 Hardware device with all software conversions plughw:CARD=PCH,DEV=7 HDA Intel PCH, HDMI 1 Hardware device with all software conversions plughw:CARD=PCH,DEV=8 HDA Intel PCH, HDMI 2 Hardware device with all software conversions Ciao, -- Martin 'Helios' Steigerwald - http://www.Lichtvoll.de GPG: 03B0 0D6C 0040 0710 4AFA B82F 991B EAAC A599 84C7 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
