Hah, um, ignore me. It seems that my c needs some work ;) In if(some_expression), I always though it is true if the expression is > 0, not != 0. If anything, that was a CodingStyle patch because it lets us see exactly what we're getting from request_irq but I can see that it is totally unnecessary :) > ----- Original Message ----- > From: "Ash Willis" <ashwillis(a)programmer.net> > To: alsa-devel(a)alsa-project.org > Subject: [alsa-devel] [PATCH] Fix request_irq error handling > Date: Sat, 14 Jul 2007 02:29:19 -0500 > > > request_irq returns 0 on success and a negative code on failure. > Many ALSA drivers incorrectly check for failure by testing for a > positive code instead of a negative one. > > Signed-Off-By: Ash Willis <ashwillis(a)programmer.net> > > > -- > We've Got Your Name at http://www.mail.com! > Get a FREE E-mail Account Today - Choose From 100+ Domains > << request_irq_error_handling.patch >> > > _______________________________________________ > Alsa-devel mailing list > Alsa-devel(a)alsa-project.org > http://mailman.alsa-project.org/mailman/listinfo/alsa-devel > -- We've Got Your Name at http://www.mail.com!

It created 4 RPMs. Two of them installed, alsa-lib and alsa-lib-devel. When I run a test on the drivers rpm, there are conflicts with the kernel headers already on the box. And I have no sound now, except in the audio configuration screen which is using the 14.rc3 packages. The packages are named with rh7 instead of fc7 as well. Do I have to run make install to get everything working, or is the header incompatability in the drivers a show stopper? Thanks.

[alsa-devel] MOTU PCI-424
by Per Eriksson 14 Jul '07

14 Jul '07

Hello, After talking to Jonathan Woithe about the development done to support MOTUs product families, Jonathan and I have reached the conclusion that ALSA support for the PCI-424 series of cards would mean a great benefit for Linux users to get high quality audio at a fair price. The PCI-424 card is used to drive the following products: MOTU 2408mk3 MOTU HD192 MOTU 24I/O The work will start this autumn, as soon as I get everything set-up, and the progress will be published on https://erinet.se/alsa/motu_pci_424/pci-424 specification.pdf The actual driver will for me be a later issue to solve, I hope to gather some understanding by reading the list and look through the releases. However, I would like some more information on how the Matrix is supposed to be used in the wiki system. Are the vendor pages only for supported devices, or also for devices concidered for being supported? Thanks, Per

[alsa-devel] [PATCH] Fix request_irq error handling
by Ash Willis 14 Jul '07

14 Jul '07

request_irq returns 0 on success and a negative code on failure. Many ALSA drivers incorrectly check for failure by testing for a positive code instead of a negative one.

[alsa-devel] [PATCH] Add quirk for HP Samba (ALC888)
by Claudio Matsuoka 13 Jul '07

13 Jul '07

Hi, This patch fixes 5.1 surround output for the HP Samba using the same quirk as the HP Lucknow. If HP machines are uniform in their wiring, I think we should rename ALC888_HP_NETTLE to ALC888_6ST_HP and ALC888_HP_LUCKNOW to ALC888_3ST_HP for generic HP 6stack and 3stack configurations. I'll probably receive more HP machines soon, so I'll see if this is the case. Best regards, Claudio

[alsa-devel] hda-intel on latext macbook pro
by Steffen Schulz 13 Jul '07

13 Jul '07

Hi all, I wrote about a week ago about the problems with alsa on the latest macbook pro (rev3, with santa-rosa). As I described, model=w2jc sort of works for the macbooks. Front Mic and LineIn work. The LineIn can be configured to LineOut by setting 2-Channe to 6-Channel. I've seen where this is done in the code and it is also possible to have a working Mic in this configuration. As I have no idea how the driver or auto-detection or driver development/reverse engineering usually works, I tried to brute force the mixer controls. I found two more mute switches, one for the front speakers and one for the LineOut. But I was unable to activate the normal headphone output. Is there anyone here who can give me a hint what to search for? I noticed that when the Mic is disabled with the code that switches between 2ch and 6ch, the Mic control do not work anymore. Maybe it is the same for the headphone controls and some other settings? This is what I got so far: [ALC882_MBP] = { .mixers = { alc882_mbp_mixer, alc882_chmode_mixer }, .init_verbs = { alc882_init_verbs, alc882_eapd_verbs, alc880_gpio1_init_verbs }, .num_dacs = ARRAY_SIZE(alc882_dac_nids), .dac_nids = alc882_dac_nids, .num_channel_mode = ARRAY_SIZE(alc880_threestack_modes), .channel_mode = alc880_threestack_modes, .need_dac_fix = 1, .input_mux = &alc882_capture_source, .dig_out_nid = ALC882_DIGOUT_NID, .dig_in_nid = ALC882_DIGIN_NID, }, static struct snd_kcontrol_new alc882_mbp_mixer[] = { HDA_CODEC_VOLUME("Master Playback Volume", 0x0c, 0x0, HDA_OUTPUT), HDA_BIND_MUTE ("Master Playback Switch", 0x0c, 2, HDA_INPUT), HDA_CODEC_MUTE ("Front Speaker Switch", 0x14, 0x00, HDA_OUTPUT), HDA_CODEC_MUTE ("Line Out Switch", 0x1a, 0x00, HDA_OUTPUT), HDA_CODEC_VOLUME("CD Playback Volume", 0x0b, 0x04, HDA_INPUT), HDA_CODEC_MUTE ("CD Playback Switch", 0x0b, 0x04, HDA_INPUT), HDA_CODEC_VOLUME("Line Playback Volume", 0x0b, 0x02, HDA_INPUT), HDA_CODEC_MUTE ("Line Playback Switch", 0x0b, 0x02, HDA_INPUT), HDA_CODEC_VOLUME("Mic Playback Volume", 0x0b, 0x0, HDA_INPUT), HDA_CODEC_MUTE ("Mic Playback Switch", 0x0b, 0x0, HDA_INPUT), HDA_CODEC_VOLUME("Mic Boost", 0x18, 0, HDA_INPUT), . . .[many controls that seem to do nothing] . { } }; I have no audio CD and no SPDIF-hardware, but the other controls do as they advertised. I would appreciate hints on finding the headphone controls. Hardware information can be seen in my last posts to the list. /Steffen -- Bildet Olsenbanden!
