[alsa-devel] How do I use SNDRV_PCM_INFO_JOINT_DUPLEX?
by Timur Tabi 19 Dec '07

19 Dec '07

I'm working on an ASoC driver. I have a limitation in my hardware that if I have an active substream, I cannot re-program the hardware registers that control the sample size. This means, for example, if I'm playing 16-bit audio, and I want to start capture, I cannot program the sample size into the hardware. My only choice is to have already programmed the capture sample size *before* I started playback. The easiest way to implement this is to make sure that the second stream has the same sample size as the first. That way, I won't need to reprogram the registers, because they'll already be programmed correctly. I discovered the SNDRV_PCM_INFO_JOINT_DUPLEX option, but I can't figure out how to use it. I know it needs to be set in my snd_pcm_hardware.info, but then what? How do I tell ALSA that the "joint" part is just that the sample sizes must be the same? -- Timur Tabi Linux kernel developer at Freescale

[alsa-devel] uniwill (0x1558, 0x9075) dup
by Andy Shevchenko 18 Dec '07

18 Dec '07

Hi! I investigated the duplicate problem and try to compare two cases. I don't deep to search of the specifications, but the current variant (with asus-laptop) should be more correct. In last HG snapshot second case already comented. I just noticed on my reseaches. -- With best regards, Andy Shevchenko. mailto: andy(a)smile.org.ua

[alsa-devel] Status of Dolby Digital on-the-fly encoding? (via a52 plugin)
by Dr. Alexander K. Seewald 18 Dec '07

18 Dec '07

I am trying to output Dolby Digital data via coaxial cable to the Logitech Z-5450 5.1 speaker set. Presumably, a52 is the right plugin for this, taking six channels and combining them into the right format. However, I cannot seem to make the Z-5450 understand the format... it always displays "No digital data" and does not output anything. Now, the documentation is very sparse on this, but states that Dolby Digital is supported, as well as DTS and DTS with 96kHz sampling rate and 24bit samples. The Z-5450 can play digital PCM stereo data, but this only activates left and right speaker (it is possible to set an effect to distribute sound to the other speakers, but this is insufficient for my purpose). I can play digital DVD 5.1 sound by attaching the coaxial cable to a DVD player. As of now, speakertest -c 6 tries to play sound on all speakers, but only left and right respond. For all other speakers, "No digital data" is displayed on the Z-5450 console. This is consistent with the Z-5450 not able to play six-channel PCM data. However, using -Dplug:a52 and .asoundrc = pcm.a52 { type a52 } (with various settings) always shows "No digital data" and no sound output. I had a sample DTS 96/24 file a while ago which was able to activate all speakers, so the data connection is ok. But sadly I have misplaced it; in any case DTS 96/24 support is not what I'd expect in the near future. Has anyone successfully output Dolby Digital (A52, AC3, ..) data via coax to the Z-5450 or a similar model? I'm using the newest alsa drivers and plugins on an 2.6.11, and the stereo-PCM output has been working for years... but this one keeps bugging me. Best, Alex -- Dr. Alexander K.

[alsa-devel] [PATCH] cs4270: wrong sample rate when CONFIG_SND_SOC_CS4270_VD33_ERRATA is set
by Timur Tabi 18 Dec '07

18 Dec '07

When CONFIG_SND_SOC_CS4270_VD33_ERRATA is set, there was a mismatch between the mclk_ratios[] and cs4270_mode_ratios[] arrays. The two arrays have been merged and code has been shuffled. One side effect is that the cs4270_set_dai_sysclk() and cs4270_set_dai_fmt() functions are available only if I2C has been enabled.

[alsa-devel] rfe: keep SND_PCI_QUIRK groups are sorted by vendor and product id pair

Hi! Some to be discussed. I found the SND_PCI_QUIRK group (lines with this macro under one structure) is unsorted. Almost in all cases no sense to make so. I wrote python script to keep lists sorted.

[alsa-devel] Is the mixer interface in the kernel protect against concurrent access?
by Hans-Christian Egtvedt 17 Dec '07

17 Dec '07

Hi, I am solving a locking bug in the at73c213 SPI sound driver, and wondered if the mixer API is protected against concurrent access in ALSA? Or should I implement a mutex to protect my hardware against concurrent access? -- Mvh Hans-Christian Egtvedt

to me but i will be glad to help you if you ask.. i don't mind compiling some other driver/kernel/tool for this just ask me one last note: searching the internet i've found this page: https://wiki.ubuntu.com/Gutsy_Intel_HD_Audio_Controller if you go down you find that the Toshiba Satellite x205-S7483 has the exact same problem here. I think they have the same card searching the Realtek web site i didn't find any 6 channel audio card with the ALC268 codec may be this mean the ALC268 is not the right codec for my audio card or this is a really new model/heavily Toshiba modified device please ask me if you need any more info or want me to do some test thanks you all for your work - -- Daniele -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHZTelgSF24OYDe4YRAm9cAJ0cWzwxUT4QZWAuTYi0ajyteb8dUgCguWlz 9rvQrAqdJBZRfHQ5yRU5PaU= =4wBW -----END PGP SIGNATURE----- - To unsubscribe from this list: send the line "unsubscribe alsa-devel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

[alsa-devel] [RFC PATCH] alsactl: skip inactive controls
by Dave Dillow 17 Dec '07

17 Dec '07

When using alsactl to save or restore the card settings, it currently skips over controls that don't have the appropriate read/write permissions. It should also skip over inactive controls, otherwise it will get an error when it tries to access that control, and will fail to save the card state (or fully restore it.) --- I noticed this while adding surround support to SiS7019. I think the problem affects other cards, as I am following the pattern used by trident, rme*, cmipci, emu10k1 and others. This is only for discussion, since I've not tested this (nor even compiled it) but I think it will fix the issue. diff -r d3ba62cd2776 alsactl/state.c --- a/alsactl/state.c Fri Dec 14 15:29:51 2007 +0100 +++ b/alsactl/state.c Sat Dec 15 14:06:35 2007 -0500 @@ -250,7 +250,8 @@ static int get_control(snd_ctl_t *handle return err; } - if (!snd_ctl_elem_info_is_readable(info)) + if (snd_ctl_elem_info_is_inactive(info) || + !snd_ctl_elem_info_is_readable(info)) return 0; snd_ctl_elem_value_set_id(ctl, id); err = snd_ctl_elem_read(handle, ctl); @@ -1306,7 +1307,8 @@ static int set_control(snd_ctl_t *handle } } - if (!snd_ctl_elem_info_is_writable(info)) + if (snd_ctl_elem_info_is_inactive(info) || + !snd_ctl_elem_info_is_writable(info)) return 0; snd_ctl_elem_value_set_numid(ctl, numid1);
