[alsa-devel] ice1712 and jack
by mike start 07 Jan '09

07 Jan '09

I've been having difficulty getting an ews88MT (ice1712 chipset) to work in full duplex using the jack audio server (jackd). Capture only mode works fine, even down to 64 samples latency, Playback only mode works fine down to 64 samples latency. Duplex mode causes 'xruns' at even 2048 samples latency. Looking at the interrupt handler, if I add some diagnostics to tell me the difference between the capture and playback DMA counters timing out I see what appears to be clock drift between the playback and capture halves of the ice1712. I also added some debug messages to show what sample rate the alsa driver was setting the hardware to and it agrees with the rate set in my jackd invocation (jackd -R -d alsa -n 2 -p 1024 - r 48000 -d hw:0,0) Also adding diagnostics to jackd to show the time spent in poll waiting for the capture and playback interrupts shows that they start in sync and gradually drift until an 'xrun' occurs when they are '-p' samples apart. According to the ice1712 data sheet the 'professional' multitrack part of this chip (the part my soundcard is using) runs its inputs and outputs from the same master clock so I'm puzzled as to why they are drifting. Does anybody have any more information relating to the ews88mt? - I think the drivers are working fine but the problems are being caused by the capture and playback not being quite in sync which renders it almost useless for professional recording. Anyone have any suggestions?

[alsa-devel] What exactly is module snd-hdsnd-hda-intel
by Nigel Henry 07 Jan '09

07 Jan '09

I see someone that had sounds working on a Thinkpad T61, but sounds have recently stopped working. The module snd-hdsnd-hda-intel is listed on his lsmod output as below. I've never seen such a module before. Any info on what this module is? lsmod | grep snd_hda_intel returns: snd_hdsnd_hda_intel 324248 2 snd_pcm 62596 2 snd_pcm_oss,snd_hda_intel snd 45604 12 snd_pcm_oss,snd_mixer_oss,snd_hda_intel,snd_pcm,snd_seq_oss,snd_seq,snd_timer,snd_seq_device snd_page_alloc 7816 2 snd_hda_intel,snd_pcm a_intel 324248 2 snd_pcm 62596 2 snd_pcm_oss,snd_hda_intel snd 45604 12 snd_pcm_oss,snd_mixer_oss,snd_hda_intel,snd_pcm,snd_seq_oss,snd_seq,snd_timer,snd_seq_device snd_page_alloc 7816 2 snd_hda_intel,snd_pcm This is on a Debian Lenny install, using kernel 2.6.26-1-686, and alsa driver version 1.0.16. Codec is AD1984. His soundcard is detected ok, as below. $ cat /proc/asound/cards 0 [Intel ]: HDA-Intel - HDA Intel HDA Intel at 0xfe020000 irq 17 This is only out of academic interest, but as modinfo shows no such module, I'm really puzzled how a non existing module can be loaded.

[alsa-devel] alsa-lib-1.0.18 doesn't build with option '--with-softfloat'
by Cliff Cai 07 Jan '09

07 Jan '09

Hi all, I'm trying to build the latest release alsa-lib-1.0.18 on Blackfin with option '--with-softfloat', but it failed with message: libtool: install: warning: remember to run `libtool --finish /usr/lib/alsa-lib/smixer' ../src/.libs/libasound.so: undefined reference to `_sqrtf' ../src/.libs/libasound.so: undefined reference to `_exp' ../src/.libs/libasound.so: undefined reference to `_log' ../src/.libs/libasound.so: undefined reference to `_sqrt' ../src/.libs/libasound.so: undefined reference to `_fmod' ../src/.libs/libasound.so: undefined reference to `_floor' Since I've selected --with-softfloat, '-lm' should be excluded from ALSA_DEPLIBS. but some source files still depend on libm, such as .../pcm/pcm_ladspa.c;.../mixer/ simple_none.c .../alisp/alisp.c.These there files cause undefined reference as above. Best Regards Cliff

[alsa-devel] [patch] nvidia hdmi audio disabled with xorg "useEdid" option
by Brian Hinz 07 Jan '09

07 Jan '09

Hi, Attached is a patch to add the IDs necessary to enable the hdmi out on an Asus P5N-EM HDMI motherboard. On a related note though, I'm trying to get this board set up as a mythtv and having some troubles getting both audio & video to work properly with my Soyo 32" LCD TV. This is probably better directed to the nvidia forums, but since I'm submitting a patch anyway I figured I'll put the question out there just in case someone knows... The issue I'm having is that the LCD TV has a huge amount of overscan in all modes, unless I direct the nVidia xorg driver to ignore the EDID, in which case the resolution is perfect but then the audio is disabled! Obviously the EDID provides the TV's audio capabilities to the X driver, and so it stands to reason that in discarding this information the audio might not work, but is there any reason to think that this could be corrected in the alsa driver somehow or does the problem lie entirely in the nvidia binary X driver? Any thoughts/suggestions would be appreciated! Thanks, -brian

[alsa-devel] Fixing the AICA driver
by Adrian McMenamin 07 Jan '09

07 Jan '09

It's about a year since I last mentioned this so I thought I'd give it another go... But the AICA sound driver I wrote for the Dreamcast still won't work properly with a pure ALSA setup and I don't know why. It works when OSS emulation is on so it appears to be some sort of interaction with the ALSA lib layer. The snd-summy driver also appears to work well with a 'pure' ALSA setup, but when (for instance) I try to replay an MP3 track without OSS emulation on I get this: Playing MPEG stream from ms.mp3 ... MPEG 1.0, Layer: III, Freq: 44100, mode: Joint-Stereo, modext: 2, BPF : 2560 Channels: 2, copyright: No, original: Yes, CRC: No, emphasis: 0. Bitrate: 128 Kbits/s, Extension value: 2 Audio: 1:1 conversion, rate: 44100, encoding: signed 16 bit, channels: 2 ALSA lib pcm_plug.c:773:(snd_pcm_plug_hw_refine_schange) Unable to find an usable access for 'default' ALSA snd_pcm_hw_params_set_access error: Invalid argument Can't find a suitable libao driver. (Is device in use?) Any clues anyone? Best wishes for 2009 and thanks for all help, Adrian

Greetings, The auto-uploading behavior of http://www.alsa-project.org/alsa-info.sh makes it act like a spyware. This makes some users - including me in the first try - astonishing and uncomfortable. I'd like to fix it by 1) adding user prompt 2) defaulting to --no-upload and introduce --upload Before going for the code, I'd like to ask for your opinions, especially on (2). Thank you. Fengguang
