This email lists some known regressions in Linus' tree compared to 2.6.20. If you find your name in the Cc header, you are either submitter of one of the bugs, maintainer of an affectected subsystem or driver, a patch of you caused a breakage or I'm considering you in any other way possibly involved with one or more of these issues. Due to the huge amount of recipients, please trim the Cc when answering.

I tried various ADPCM formats which gave correct playback speed, but much noise. There seems to be a Media Vision ADPCM format, which is probably what the Jazz16 wants, but I have no information about that format. FWIW, the playback_format/capture_format values I've tried are: #define SB_DSP_ALAW_OUTPUT_AUTO 0x1F #define SB_DSP_ALAW_INPUT_AUTO 0x2F #define SB_DSP_ULAW_OUTPUT_AUTO 0x7f #define SB_DSP_ULAW_INPUT_AUTO 0x8f #define SB_DSP_ADPCM_OUTPUT_AUTO 0x7C+1 #define SB_DSP_ADPCM_INPUT_AUTO 0x8C+1 > > Setting the irq of the MPU-401 port requires the SB part to be active and > > even worse, DSP commands need to be sent.

It's fine with non-irq version (which > uses timer) if the code gets too complicated, of course. It turned out that I can't disable just the MPU port. -- Rask Ingemann Lambertsen

[alsa-devel] [PATCH] PnP: Protocol for Media Vision Jazz16 sound cards

From: Rask Ingemann Lambertsen <rask(a)sygehus.dk> - Add code to detect and PnP protocol to manage Media Vision Jazz16 sound cards. Tested with a Jazz16 based sound card and Linux 2.6.20.

[alsa-devel] Can't subscribe to the list

Hi, I've tried 3 times over the last week or so to subscribe to this list with no success. I can't believe I'm doing anything wrong (how hard is it?), but I don't see any posts (in the archives) indicating any problems subscribing, so I'm at a loss. Any suggestions? Or can you subscribe me manually? Thanks, Ed

[alsa-devel] Support for Compal EL81 (Intel HDA/Realtek alc883)

Good evening. I am the lucky owner of a nice Compal EL80 laptop, sporting an Intel HDA audio controller with realtek alc883. Here is what I get with lspci -vvv: 00:1b.0 Audio device [0403]: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller [8086:27d8] (rev 02) Subsystem: COMPAL Electronics Inc Unknown device [14c0:0017] Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 0, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 22 Region 0: Memory at d2500000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Flags: PMEClk- DSI- D1- D2- AuxCurrent=55mA PME(D0+,D1-,D2-,D3hot+,D3cold+) Status: D0 PME-Enable- DSel=0 DScale=0 PME- Capabilities: [60] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable- Address: 0000000000000000 Data: 0000 Capabilities: [70] Express Unknown type IRQ 0 Device: Supported: MaxPayload 128 bytes, PhantFunc 0, ExtTag- Device: Latency L0s <64ns, L1 <1us Device: Errors: Correctable- Non-Fatal- Fatal- Unsupported- Device: RlxdOrd- ExtTag- PhantFunc- AuxPwr- NoSnoop+ Device: MaxPayload 128 bytes, MaxReadReq 128 bytes Link: Supported Speed unknown, Width x0, ASPM unknown, Port 0 Link: Latency L0s <64ns, L1 <1us Link: ASPM Disabled CommClk- ExtSynch- Link: Speed unknown, Width x0 Capabilities: [100] Virtual Channel Capabilities: [130] Unknown (5) I had very elementary operativity, but missed much, including for example microphone boost.

With the first example, the only one that is commented in (copied from LAPTOP_EAPD), I could obtain a working microphone boost. The thing is far from perfect, though. Suffice to say that I find the main volume in the cursor labeled 'Surround' in alsamixer. Is there any instruction about how to obtain the right information to configure this laptop of mine? Can you help? In this case, what other information may I provide? Thanks in advance Carlo - Den Haag, NL -- * Se la Strada e la sua Virtu' non fossero state messe da parte, * K * Carlo E.

[alsa-devel] ftp.alsa-project.org
by Rene Herman 26 Mar '07

Hi Jaroslav. When you currently want to download a complete new release from ftp.alsa-project.org you have to scrounge around all the directories manually. Would it be easy to automate to have a /pub/alsa/<version>/ directory containing links to all the relevant packages? Ie: /pub/alsa/1.0.13/alsa-driver-1.0.13.tar.bz2 -> ../../driver/alsa-driver-1.13.tar.bz2 and same: alsa-lib-1.0.13.tar.bz2 -> ../../lib/alsa-lib-1.13.tar.bz2 alsa-plugins-1.0.13.tar.bz2 -> ../../plugins/alsa-plugins-1.13.tar.bz2 alsa-utils-1.0.13.tar.bz2 -> ../../utils/alsa-utils-1.13.tar.bz2 alsa-tools-1.0.13.tar.bz2 -> ../../tools/alsa-tools-1.13.tar.bz2 alsa-firmware-1.0.13.tar.bz2 -> .../firmware/alsa-firmware-1.13.tar.bz2 alsa-oss-lib-1.0.12.tar.bz2 -> ../../oss-lib/alsa-oss-lib-1.12.tar.bz2 with probably links /pub/alsa/stable -> 1.0.13 and /pub/alsa/devel -> 1.14rc3 and stuff like that. (by the way, as far as I'm concerned, the /pub/alsa locations wouldn't need to be links but could just as well be the main locations but if you want to keep the current layout in place...) Would make it a bit nicer to download a new release... Rene.

[alsa-devel] Patch to p5vdc-x motherboard's sound
by sergiodaniel＠inf.ufg.br 26 Mar '07

26 Mar '07

This is a description to correct the problem of p5vdc-x motherboard's. In file hda_codec.c the line 1727 is: if (codec->bus->modelname && models) { the variable codec->bus->modelname not is reconized for asus pc5vdc-x motherboards. Your ship is "Analog Devices AD1986A" i correct this add the lines in the funcion static int patch_ad1986a(struct hda_codec *codec) . . . default: spec->num_mixers = 2; spec->mixers[1] = ad1986a_3st_mixers; spec->num_init_verbs = 3; spec->init_verbs[1] = ad1986a_3st_init_verbs; spec->init_verbs[2] = ad1986a_ch2_init; spec->channel_mode = ad1986a_modes; spec->num_channel_mode = ARRAY_SIZE(ad1986a_modes); spec->need_dac_fix = 1; spec->multiout.max_channels = 2; spec->multiout.num_dacs = 1; break; } The complete code is in www.inf.ufg.br/~sergiodaniel/alsa-driver-1.0.14_PATCH_rc3-p5vdc-x.tar.gz thank's..
