[RESEND] Dom0 sound problem with Hypervisor 4.1.3~rc1+hg-20120614.a9c0a89c08f2-5
Would appreciate if someone can throw some light on this: Happily running a Xen system, most problems sorted out, except sound. The onboard sounds works fine when Linux is booted, but is completely silent when the same kernel is booted as Dom0. ALSA devices and modules are identical in both cases. The only difference I can find in the dmesg is: With Xen: |xen: registering gsi 22 triggering 0 polarity 1 |xen: --> pirq=22 -> irq=22 (gsi=22) |snd_hda_intel 0000:00:1b.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22 |snd_hda_intel 0000:00:1b.0: setting latency timer to 64 |input: HDA Digital PCBeep as /devices/pci0000:00/0000:00:1b.0/input/input7 With Linux: |snd_hda_intel 0000:00:1b.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22 |snd_hda_intel 0000:00:1b.0: irq 50 for MSI/MSI-X |snd_hda_intel 0000:00:1b.0: setting latency timer to 64 |input: HDA Digital PCBeep as /devices/pci0000:00/0000:00:1b.0/input/input9 lspci: |00:1b.0 Audio device: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller (rev 04) | Subsystem: Intel Corporation Device 2040 | Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ | Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort+ >SERR- <PERR- INTx- | Latency: 0, Cache Line Size: 64 bytes | Interrupt: pin A routed to IRQ 304 | Region 0: Memory at f7f30000 (64-bit, non-prefetchable) [size=16K] | Capabilities: <access denied> | Kernel driver in use: snd_hda_intel Running on Debian Testing (Wheezy). xen-hypervisor-4.1-i386 4.1.3~rc1+hg-20120614.a9c0a89c08f2-5 Xen Hypervisor on i386 linux-image-3.2.233-rt37 3.2.233-rt37-10.00.Custom Linux kernel binary image for version 3.2.233-rt37 The kernel is custom (to fix i915 GPU hung problem), but I''ve tried the same with the stock kernels with no difference.

Have you tried without the -rt patches?
