https://bugzilla.novell.com/show_bug.cgi?id=282223 Summary: Sound card woking only from headphones on HP DC7700 Product: openSUSE 10.2 Version: Final Platform: i386 OS/Version: openSUSE 10.2 Status: NEW Severity: Major Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: leandro.gelasi@tiscali.it QAContact: qa@suse.de I recently get assigned a brand new HP DC7700 PC, from a very big public supply (over 15.000 PCs - bought by CONSIP - Italy). All these PCs will be assigned to Italian public agencies. I installed OpenSuSE 10.2 and all went fine, except for the soundcard that worked only from headphones and have non-functional mixer settings.

I patched SuSE Linux kernel source, adding that PCI ID, and recompiled the kernel. All solved! Now the audio board works perfectly. My patch is applied versus /usr/src/linux/sound/pci/hda/patch_realtek.c (from kernel-source-2.6.18.8-0.3.rpm): ---- patch start here ------ 5779a5780,5781

{ .pci_subvendor = 0x103c, .pci_subdevice = 0x2802, .config = ALC262_HP_BPC }, /* dc7700 */

---- patch ends here ------ I merely copied a similar section made for HP XWxxxx workstation, changing the subdevice ID. I suggest Novell to make an updated kernel package to address this problem, considering that this specific PC will be at the hand of 15.000 Italian public officers. Thanks for your attention.
