[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!

[alsa-devel] snd-hda-intel auto detect incorrect
by Matt Hirsch 12 Jul '07

12 Jul '07

I have an hp pavilion tx 1000 laptop running fedora 7. The auto detect feature of the snd-hda-intel dirver doesn't work on my sound card. As requested in Documentation/sound/alsa/ALSA-Configuration.txt I am forwarding the following to the developer mailing list: #uname -a Linux laptop 2.6.21-1.3228.fc7 #1 SMP Tue Jun 12 14:56:37 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux # lspci -s 00:10.1 00:10.1 Audio device: nVidia Corporation MCP51 High Definition Audio (rev a2) # lspci -s 00:10.1 -nv 00:10.1 0403: 10de:026c (rev a2) Subsystem: 103c:30bf Flags: bus master, 66MHz, fast devsel, latency 0, IRQ 17 Memory at c0000000 (32-bit, non-prefetchable) [size=16K] Capabilities: [44] Power Management version 2 Capabilities: [50] Message Signalled Interrupts: Mask+ 64bit+ Queue=0/0 Enable- Capabilities: [6c] HyperTransport: MSI Mapping # yum list alsa-\* Installed Packages alsa-lib.x86_64 1.0.14-0.4.rc3.fc7 installed alsa-lib.i386 1.0.14-0.4.rc3.fc7 installed alsa-utils.x86_64 1.0.14-0.7.rc2.fc7 installed With no options I get the following log message and the audio doesn't work: kernel: hda_codec: Unknown model for ALC660VD/ALC861VD, trying auto-probe from BIOS... When loading the module as follows, the audio works: modprobe snd-hda-intel model=3stack I believe the card was detected as 3stack-dig, as the alsamixer options match when either no option or model=3stack-dig are given. Hope this helped. Thanks for all your hard work! Matt

[alsa-devel] Period Size in hw_params
by Paul Kavan 12 Jul '07

12 Jul '07

I finally have my basic audio applications working. I divided it into capture and playback and began with playback as I had a nice sinewave I could use to playback. Anyway, I think my hangup with getting the thing working was with the buffer and period information. My apps now do this: int periods = 2; /* Number of periods */ snd_pcm_uframes_t periodsize = 1000; /* Periodsize (bytes) */ /* Set number of periods */ if (snd_pcm_hw_params_set_periods(pcm_handle, hwparams, periods, 0) < 0) { fprintf(stderr, "Error setting periods.\n"); return(-1); } /* Set buffer size */ size = periodsize * periods; if (snd_pcm_hw_params_set_buffer_size(pcm_handle, hwparams, (size)>>2) < 0) { fprintf(stderr, "Error setting buffer size.\n"); return(-1); } I borrowed the period size from using aplay -v and seeing what it used. Setting number of periods to 2 was a little bit of guess work based on what others seem to use. I have looked at the alsa documentation and cannot see how I could have determined these numbers would have worked without trial and error. Can anyone either give me a explanation of how to determine these or a pointer to some decent documentation that talks about this? Thanks.
