Date: Sun, 7 Mar 2010 11:21:38 -0800 From: VDR User <user.vdr@...il.com> To: Wei Ni <wni@...dia.com> Cc: Takashi Iwai <tiwai@...e.de>, akpm <akpm@...ux-foundation.org>, alsa-devel <alsa-devel@...a-project.org>, Wu Fengguang <fengguang.wu@...el.com>, linux-kernel <linux-kernel@...r.kernel.org>, Pavel Hofman <pavel.hofman@...ite.cz> Subject: Re: [alsa-devel] [PATCH]Support MCP89 and GT21x hdmi audio I think this may be relevant to this subject, if not then my apologies. I've just installed a GT220 card and was able to get audio-over-hdmi working by compiling the snapshot drivers from 20100307 which contain Wei's new code. I further had to patch the driver to recognize my card with: --- alsa-driver-orig/alsa-kernel/pci/hda/patch_nvhdmi.c 2010-03-06 18:00:12.000000000 -0800 +++ alsa-driver/alsa-kernel/pci/hda/patch_nvhdmi.c 2010-03-06 18:02:00.000000000 -0800 @@ -1335,6 +1335,8 @@ static struct hda_codec_preset snd_hda_p .patch = patch_nvhdmi_8ch_89 }, { .id = 0x10de000b, .name = "GT21x HDMI", .patch = patch_nvhdmi_8ch_89 }, + { .id = 0x10de000a, .name = "GT220 HDMI", + .patch = patch_nvhdmi_8ch_89 }, { .id = 0x10de000d, .name = "GT240 HDMI", .patch = patch_nvhdmi_8ch_89 }, {} /* terminator */ @@ -1347,6 +1349,7 @@ MODULE_ALIAS("snd-hda-codec-id:10de0006" MODULE_ALIAS("snd-hda-codec-id:10de0007"); MODULE_ALIAS("snd-hda-codec-id:10de0067"); MODULE_ALIAS("snd-hda-codec-id:10de8001"); +MODULE_ALIAS("snd-hda-codec-id:10de000a"); MODULE_ALIAS("snd-hda-codec-id:10de000c"); MODULE_ALIAS("snd-hda-codec-id:10de000b"); MODULE_ALIAS("snd-hda-codec-id:10de000d"); This seems to work fine when running VDR but if I do anything else like upgrade packages, compile something, or maybe create a bz2, then I start to see _a lot_ of the following in my xine log: pcm_hw.c: snd_pcm_hw_delay() SNDRV_PCM_IOCTL_DELAY failed. With the old code this didn't happen. However, my setup was an 8400gs using SPDIF OUT from my mainboard to SPDIF IN on the card. Then using a dvi->hdmi cable into the tv. Again, I apologize if I'm posting this in the wrong place.
