** Summary changed: - Intel 82801H sound card speakers not working + [Intel 82801H] sound card volume inaudibly low unless model=mitac specified
** Description changed: I've tried everything to get this sound working. Headphones work fine, they're loud and clear, but speakers don't work at all. I've recompiled from alsa-source. I've recompiled from source files direct from ALSA. I've tried adding various options in /etc/modprobe.d/alsa-base. Nothing works. What's more, alsamixer doesn't work. Whenever I try to run alsamixer, it spits an error back at me (listed below), so I can't tell if the speaker channel is just muted or not. I'm running Kubuntu Hardy Beta, however the same problem occurred in Gutsy. sudo lspci -vv ... 00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03) Subsystem: Mitac Unknown device 8227 Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 0, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 22 Region 0: Memory at fc200000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Flags: PMEClk- DSI- D1- D2- AuxCurrent=55mA PME(D0+,D1-,D2-,D3hot+,D3cold+) Status: D0 PME-Enable- DSel=0 DScale=0 PME- Capabilities: [60] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable- Address: 0000000000000000 Data: 0000 Capabilities: [70] Express Unknown type IRQ 0 Device: Supported: MaxPayload 128 bytes, PhantFunc 0, ExtTag- Device: Latency L0s <64ns, L1 <1us Device: Errors: Correctable- Non-Fatal- Fatal- Unsupported- Device: RlxdOrd- ExtTag- PhantFunc- AuxPwr- NoSnoop+ Device: MaxPayload 128 bytes, MaxReadReq 128 bytes Link: Supported Speed unknown, Width x0, ASPM unknown, Port 0 Link: Latency L0s <64ns, L1 <1us Link: ASPM Disabled CommClk- ExtSynch- Link: Speed unknown, Width x0 ... aplay -l card 0: Intel [HDA Intel], device 0: ALC883 Analog [ALC883 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: Intel [HDA Intel], device 1: ALC268 Digital [ALC268 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: Intel [HDA Intel], device 5: ALC268 Analog [ALC268 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 alsamixer ALSA lib simple_none.c:1491:(simple_add1) helem (MIXER,'Headphone Playback Switch',0,2,0) appears twice or more alsamixer: function snd_mixer_load failed: Invalid argument cat /proc/asound/modules 0 snd_hda_intel + + [Update] + A patch was provided on the uptstreamed bug which resolves the issue. The issue seems to be that the 82801H (8086:284b) is really a rebranded mitac card but the driver doesn't pick this up properly. This patch is included in Ubuntu now, but you have to append the following to your /etc/modprobe.d/alsa-base: + + options snd-hda-intel model=mitac + + For those on older Ubuntu versions like Hardy, you'll need to hand-patch + your alsa-driver to gain the support.
