Dear ALSA users,
could please enlighten me regarding the following problem.
According to `lspci` my ASUS M2V-MX SE mainboard uses a VIA VT1708/A
audio chipset.
$ lspci -vvnn | grep -A10 Audio
20:01.0 Audio device [0403]: VIA Technologies, Inc. VT1708/A [Azalia HDAC] (VIA High Definition Audio Controller) [1106:3288] (rev 10)
Subsystem: ASUSTeK Computer Inc. Device [1043:8290]
Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx-
Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
Latency: 0, Cache Line Size: 64 bytes
Interrupt: pin A routed to IRQ 17
Region 0: Memory at fbffc000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel driver in use: HDA Intel
But it is reported for example by PulseAudio as a VIA VT82xx device.
Noticing that `snd_hda_codec_realtek` gets loaded adds even more to my
confusion.
$ lsmod | grep snd
snd_hda_codec_realtek 234615 1
snd_hda_intel 18147 4
snd_hda_codec 53876 2 snd_hda_codec_realtek,snd_hda_intel
snd_hwdep 5220 1 snd_hda_codec
snd_pcm_oss 32223 0
snd_mixer_oss 12478 1 snd_pcm_oss
snd_pcm 60263 4 snd_hda_intel,snd_hda_codec,snd_pcm_oss
snd_seq_midi 4064 0
snd_rawmidi 15083 1 snd_seq_midi
snd_seq_midi_event 4628 1 snd_seq_midi
snd_seq 41041 2 snd_seq_midi,snd_seq_midi_event
snd_timer 15406 2 snd_pcm,snd_seq
snd_seq_device 4477 3 snd_seq_midi,snd_rawmidi,snd_seq
snd 44158 18 snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_rawmidi,snd_seq,snd_timer,snd_seq_device
soundcore 4566 1 snd
snd_page_alloc 6105 2 snd_hda_intel,snd_pcm
Even more since there is a `snd-hda-codec-via.ko` available.
$ ls /lib/modules/2.6.32-trunk-amd64/kernel/sound/pci/hda/
snd-hda-codec-analog.ko
snd-hda-codec-atihdmi.ko
snd-hda-codec-ca0110.ko
snd-hda-codec-cirrus.ko
snd-hda-codec-cmedia.ko
snd-hda-codec-conexant.ko
snd-hda-codec-idt.ko
snd-hda-codec-intelhdmi.ko
snd-hda-codec.ko
snd-hda-codec-nvhdmi.ko
snd-hda-codec-realtek.ko
snd-hda-codec-si3054.ko
snd-hda-codec-via.ko
snd-hda-intel.ko
Is the correct module loaded? I wanted to get this question answered
first before I asked more questions regarding my problem with PulseAudio
[1].
I am using Debian Sid/unstable with the following Linux kernel
$ uname -a
Linux hostname 2.6.32-trunk-amd64 #1 SMP Sun Jan 10 07:51:13 UTC 2010 x86_64 GNU/Linux
but a 32-bit userspace with `libasound2` 1.0.21a-1 installed.
$ more /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.21.
Thanks,
Paul
