Re: [alsa-devel] No headphone output on HT Omega Claro Halo

I have an HT Omega Claro Halo (CMI8878) card that is not entirely working. This card has two analog outputs, a pair of RCA connectors and also a separate headphone output (3.5mm jack). The RCA outputs work, but the headphone output, which notably passes a signal from a built in headphone amp, does not.

Please try this patch:
